"Now what happens then when you introduce technology into production? You produce enormous quantities of goods by technological methods, but at the same time you put people out of work. You can say, "Oh but it always creates more jobs. There will always be more jobs." Yes, but lots of them will be futile jobs. They will be jobs making every kind of frippery and unnecessary contraption, and one will also at the same time have to beguile the public into feeling that they need and want these completely unnecessary things that aren't even beautiful. And therefore an enormous amount of nonsense employment and busy work, bureaucratic and otherwise, has to be created in order to keep people working, because we believe, as good Protestants, that the devil finds work for idle hands to do. But the basic principle of the whole thing has been completely overlooked, that the purpose of the machine is to make drudgery unnecessary. And if we don't allow it to achieve its purpose, we live in a constant state of self-frustration. So then, if a given manufacturer automates his plant and dismisses his labor force, and they have to operate on a very much diminished income (say, some sort of dole), the manufacturer suddenly finds that the public does not have the wherewithal to buy his products. And therefore he has invested in this expensive automotive machinery to no purpose. And therefore obviously the public has to be provided with the means of purchasing what the machines produce. People say, "That's not fair. Where's the money going to come from? Who's gonna pay for it?" The answer is the machine. The machine pays for it, because the machine works for the manufacturer and for the community."

"What is peculiar and new to the [19th] century, differentiating it from all its predecessors, is its technology. It was not merely the introduction of some great isolated inventions. It is impossible not to feel that something more than that was involved. ... The process of change was slow, unconscious, and unexpected. In the nineteeth century, the process became quick, conscious, and expected. ... The whole change has arisen from the new scientific information. Science, conceived not so much in its principles as in its results, is an obvious storehouse of ideas for utilisation. ... Also, it is a great mistake to think that the bare scientific idea is the required invention, so that it has only to be picked up and used. An intense period of imaginative design lies between. One element in the new method is just the discovery of how to set about bridging the gap between the scientific ideas, and the ultimate product. It is a process of disciplined attack upon one difficulty after another This discipline of knowledge applies beyond technology to pure science, and beyond science to general scholarship. It represents the change from amateurs to professionals. ... But the full self-conscious realisation of the power of professionalism in knowledge in all its departments, and of the way to produce the professionals, and of the importance of knowledge to the advance of technology, and of the methods by which abstract knowledge can be connected with technology, and of the boundless possibilities of technological advance,—the realisation of all these things was first completely attained in the nineteenth century."

"Some 20 years after Lumière’s film, a Harvard psychologist named Hugo Munsterberg challenged researchers to figure out the depth of, and reason for, cinema’s influence: “For the first time the psychologist can observe the starting of an entirely new esthetic development, a new form of true beauty in the turmoil of a technical age, created by its very technique and yet more than any other art destined to overcome outer nature by the free and joyful play of the mind,” Munsterberg wrote in The Photoplay: A Psychological Study, considered by many to be the first important behavioral look at film. But though the research gauntlet had been thrown down, what followed is what one would expect when looking for artistry in a Pauly Shore flick: nothing. Or, at least, very little, says Stuart Fischoff, founder of the Journal of Media Psychology, who in 2003 retired from the psychology department at California State University, Los Angeles. Between 1916, when Munsterberg wrote The Photoplay, and the 1950s, perhaps the most influential psychological research on cinema was L.L. Thurnstone’s 1928 Payne Fund report — a study whose purpose was to indict, not investigate, the role of film on behavior, Fischoff says. In fact, for much of the 20th century, the psychological study of film was considered “lightweight stuff,” says Dolf Zillmann, University of Alabama, one of the field’s pioneers. Film study was approached with a Freudian mindset, and few empirical studies took place. But in the past decade or so, such research has experienced a resurgence — the rare sequel that outperforms the original. “There’s really a new psychology of film in the making,” says Zillmann. Film study from a psychological perspective now takes place in campuses around the country, combining interdisciplinary approaches from several areas, with an increasing focus on the neuroscience of viewer response."

"White examines the hold of analogical reasoning on the legal imagination by assessing the way courts responded to innovations in the social world. The two examples that are the subject of this essay are the treatment of radio and motion pictures in the early part of the twentieth century. He looks at how law responded to these innovations and, in particular, how courts responded to challenges to efforts to impose a regulatory regime on them. The drive to regulate emerged from a particular awareness of the media’s mass quality and the immediacy of the effects they created; in addition, it was fueled by the Progressive Era’s tendency to approve regulation by experts as a way of addressing social concerns. Yet these regulations, at least from the perspective of today, raise serious First Amendment issues. White examines cases challenging regulation to show that analogical reasoning was used to construct a legal history in such a way as to justify regulation in spite of the First Amendment. In the case of film, courts constructed such a history by categorizing it as a form of property. Like property, film might be used to do “evil.” Courts then conjured the history of the “police powers” by which states could invoke their powers to protect the morals of the public. In addition, they brought the regulation of film within the history of administrative law and, as a result, focused only on the nature of the legislative delegation involved. Having established framework of analogies, courts then were able to bring to bear the relevant precedents. In their treatment of those cases they tended to anticipate the position of Marshall in “Payne”, insisting on the value of consistency and continuity of law’s doctrinal structure."

"It could be that today's conservative movement remains in thrall to the same narrative that has defined its attitude toward film and the arts for decades. Inspired by feelings of exclusion after Hollywood and the popular culture turned leftward in the '60s and '70s, this narrative has defined the film industry as an irredeemably liberal institution toward which conservatives can only act in opposition—never engagement. Ironically, this narrative ignores the actual history of Hollywood, in which conservatives had a strong presence from the industry's founding in the early 20th century up through the '40s, '50s and into the mid-'60s]. The conservative Hollywood community at that time included such leading directors as Howard Hawks, Frank Capra, and Cecil B. DeMille, and major stars like John Wayne, Clark Gable, and Charlton Heston. These talents often worked side by side with notable Hollywood liberals like directors Billy Wilder, William Wyler, and John Huston, and stars like Humphrey Bogart, Lauren Bacall, and Spencer Tracy. The richness of classic Hollywood cinema is widely regarded as a testament to the ability of these two communities to work together, regardless of political differences. As the younger, more left-leaning "New Hollywood" generation swept into the industry in the late '60s and '70s, this older group of Hollywood conservatives faded away, never to be replaced. Except for a brief period in the '80s when the Reagan Presidency led to a conservative reengagement with film—with popular stars like Clint Eastwood, Sylvester Stallone, and Arnold Schwarzenegger making macho, patriotic action films—conservatives appeared to abandon popular culture altogether. In the wake of this retreat, conservative failure to engage with Hollywood now appears to have been recast by today's East Coast conservative establishment into a generalized opposition toward film and popular culture itself. In the early '90s, conservative film critic Michael Medved codified this oppositional feeling toward Hollywood in his best-selling book Hollywood vs. America."

"It would probably not be beyond human ingenuity to write books by machinery. But a sort of mechanizing process can already be seen at work in the film and radio, in publicity and propaganda, and in the lower reaches of journalism. The Disney films, for instance, are produced by what is essentially a factory process, the work being done partly mechanically and partly by teams of artists who have to subordinate their individual style. Radio features are commonly written by tired hacks to whom the subject and the manner of treatment are dictated beforehand: even so, what they write is merely a kind of raw material to be chopped into shape by producers and censors. So also with the innumerable books and pamphlets commissioned by government departments. Even more machine-like is the production of short stories, serials, and poems for the very cheap magazines. Papers such as the Writer abound with advertisements of literary schools, all of them offering you ready-made plots at a few shillings a time. Some, together with the plot, supply the opening and closing sentences of each chapter. Others furnish you with a sort of algebraical formula by the use of which you can construct plots for yourself. Others have packs of cards marked with characters and situations, which have only to be shuffled and dealt in order to produce ingenious stories automatically. It is probably in some such way that the literature of a totalitarian society would be produced, if literature were still felt to be necessary. Imagination — even consciousness, so far as possible — would be eliminated from the process of writing. Books would be planned in their broad lines by bureaucrats, and would pass through so many hands that when finished they would be no more an individual product than a Ford car at the end of the assembly line. It goes without saying that anything so produced would be rubbish; but anything that was not rubbish would endanger the structure of the state. As for the surviving literature of the past, it would have to be suppressed or at least elaborately rewritten."

"Until about the mid-1930s, law in film was an authoritative and neutral process—a formal and almost religious space—in which truth could be revealed or justice done through heavy-handed elites. Starting from the late-1930s until the post-WWII period—the "film noir" period—film depicted an underside of law, corruption, and unreasonable attachment to formality at the expense of justice. There are a lot of films from this time that depict legal heroes that flout the law to make sure the truth comes out and that depict mobs taking over both the legal process and civil society. In the mid-1950s onward, classical Hollywood cinema took over with its brighter depiction of the promise of law to help the everyday person. It is an evolution that sounds in grassroots democracy, the value of juries, and the promise of individuals to make a difference working within the system. From the late-1980s, many law films were ahead of their time in terms of civil rights, depicting African American judges, female litigators, and a legal system that is open and sufficiently self-reflective to incorporate criticism into its pursuit of justice. You might think of Philadelphia, with Tom Hanks and Denzel Wasghinton, as one of these films, or A Few Good Men, with Demi Moore as Lt. Cmdr. Joanne Galloway and J.A. Preston as Judge Julius Alexander Randolf. TV has followed a similar arc, but with more police serials than courtroom dramas. As you can see from these periods, the themes of film track and help constitute U.S. socio-political culture."

"The Preamble of the UNESCO Convention on the Protection and Promotion of Diversity of Cultural Expressions reads, “Linguistic diversity is a fundamental element of cultural diversity” (UNESCO, 2005). Albornoz and García Leiva (2016) state that advocating linguistic diversity is an imperative for the international community, as every language reflects a one-of-a-kind vision of the world, with its own value system, its specific philosophy and its particular cultural characteristics. A language provides support to an identity and is an essential element of an irreplaceable cultural wealth. Feature films, as well as other cultural expressions, provide a channel of expression and dissemination for approximately 6,000 languages which are spoken in the world.11Asseveral studies have pointed out (Ranaivoson, 2007; UIS, 2011), diversity is a multidimensional concept. Stirling’s definition (1998, 2007) of diversity includes a combination of three components: variety, balance and disparity. Variety refers to the number of different categories defined; specifically for films, we may ask, how many languages can be identified in the cinematographic production of a country? Balance refers to the extent to which these categories are represented: what percentages of each language are used in films? And disparity refers to the degree of dissimilarity that exists between the different categories: how different are the languages used? Thus, the larger the number of categories and the more balanced and disparate the categories, the more diverse the system."

"In 2012, the number of feature films greatly increased throughout the world, and the following year a new production record was hit: 7,610 movies. However, the sustained growth of global production during the 2005-2013 period has not undermined the weight of the main production countries: India, the United States, China, Japan and most Western European countries, including the United Kingdom, France, Germany and Spain. This finding, in the attempt to analyse the diversity of sources, reveals a high degree of concentration of production in the economic superpowers and in some of the most heavily-populated countries of the world. A special case in point is India, the country with the second-largest population, and the number-one film making country, which is experiencing a major growth in production. India produced 1,041 movies in 2005 to 1,724 movies in 2013. The number of feature films produced in 2013, mostly with digital technology and at multiple sites, represented over one-fifth of worldwide production. International feature film co-productions, driven by the public sector and private production companies, were common in some countries of Western Europe and the United States. France had the largest number of co-productions in the 2012-2013 biennium. Production companies view co-productions with companies from other countries as a means of taking advantage of the film making grant programmes of various countries and of extending the reach of films. Increased production does not necessarily lead to a better and larger dissemination of films. The dominant positions of the U.S. majors in many markets directly impact the diversity offered,i.e.what content reaches the screens and how. For instance, the European space, comprising countries with a prominent tradition for production, repeatedly expresses the lack of reach of its feature films across borders . Most countries have monolingual (in their respective official languages) or bilingual film production. Again, India stands out for the wide spectrum of local languages in its movies, none of which has a share over 17%. In countries with multilingual film production, there are one or several drivers for this: a historical presence of different social groups within the country and/or large migrant groups, geo-cultural proximity with companies speaking other languages, and the development of strategies for commercial penetration in new markets, among others. Dubbing policies implemented by countries are unfavourable for the recognition of languages other than those of the place where foreign films are screened."

"According to the three categories in the UIS 2014 Questionnaire on Feature Film Statistics, there is a clear pre-eminence of fiction feature films versus documentaries and animation movies. Additionally, all countries offering information on the production of fiction, animation and documentary feature films show a clear imbalance among the categories. There is a strong geographic concentration of the revenues from the commercial screening of feature films in theatres. The top 10 markets, led by the United States/Canada, China and Japan, held three-fourths of global revenues during the 2012-2013 period. China, the most heavily-populated country in the world, is seeing a sustained increase in its gross box office for feature films in theatres (in 2013, it exceeded US$3.6billion). It appears that the world’s second film market in terms of gross box office is ready to overcome, in the near future, the stagnated market of the United States/Canada. India, with average ticket prices well below those prevailing in the top revenue markets, is the top country in terms of volume of tickets sold. In 2012, Indian theatres received more theatre goers than the United States, China and Japan together. Even though there are noticeable differences between countries and inside countries at the global level during 2012 and 2013, the average price of theatre tickets continued to grow. The 2005-2013 period saw an increase of 40% in the average ticket price. The most popular feature films watched in theatres in 2012 and 2013 confirm a very high concentration of consumption of blockbusters produced (or co-produced) and distributed by U.S. majors. They are mostly action/adventure movies, some with animation techniques, targeting children and adolescents, supported by multi-million budgets and international advertising campaigns. As has been the case in recent years, mass consumption of feature films in theatres has favoured the franchises of various series and bringing to the big screen stories that were originally created as [[comics."

"Over the few last decades, the rate of economic growth of the Chinese economy has been enormous compared to most,if not all,economies in developed countries. As a result, this growth has been evident in the film market, where by 2012 China became the second largest consumer of feature films in the world in terms of box office.During the same period, the USA market has faced stagnation or experienced little increase in terms of admissions. If this trend continues, China will surpass the USA as the world’s Number 1film market by 2020.The film market in China has grown four to five times faster than its GDP over the last decade (and its GDP is one of the fastest growing in the world)and the growth in the film market has been even more impressive. In fact, between 2005 and 2011, box office in China grew on average by 43% per year (50% over the 2008-2011 period), while the cinema market box office of the USA grew on average by just 2.2% annually (see Figure 5). The difference in the number of admissions is remarkable: while admissions grew on average by 15.6% annually in China between 2005 and 2011, in the USA market there was an annual average decrease of -1.4% (see Figure 6). This growth occurred despite the dramatic increase in ticket prices that occurred in China during this period. The average admission price in China multiplied 3.5 times, an increase of 253% between 2005 and 2011, whereas the average ticket price in the USA increased by only 23.8%."

"Viewers in Latin America have access to about 9,756 screens. On average,there are 210 commercial releases per year. Depending on the country, between 5 and 130 national films are produced a year, primarily as a direct result of the national support received by the governments of the region over various decades. During the first decade of the 21st Century, Latin American countries produced 2,400 feature films (see Figure 8), with growth throughout each decade (on average 350 films were produced per year between 2005 and 2011). This is a sharp increase from the 1980s, when on average 230 films were produced annually or the 1990s with 90 films per year (Getino, 2005). Film production in Latin America increased partly as a direct result of the public policies developed to support the field (with the exceptions of Paraguay and a few Central American countries). These policies have been present in most of the subcontinent since the 1930s (mainly in Argentina, Brazil, Mexico and Peru). The subsequent decades saw further support in the form of subsidies, tax incentives,soft loans, prizes for quality and screen quotas (there were even state producers, state distributors and state exhibitors, mainly in Mexico from the 1940s to 1970s and in Brazil in the 1970s). In the early 1990s, most countries in the region experienced a drastic reduction in public support, affecting the national film sectors negatively. Nevertheless, in the late 1990s and early 2000s, there was a re-emergence of public policies favorable to the film sector, mainly in relation to production. The three major film-producing countries, Argentina, Brazil and Mexico,resumed their growth. During the 2000s, most Latin American countries implemented national legislation supporting the film sector. Argentina and Brazil returned to maximum production peaks with over 100 films produced annually, surpassing records set in the earlier “golden years”. Mexico also increased film production, but the country is only just reaching the number of films produced during its golden years (between 1940 and 1980), which was also about 100 annually. Other Latin American countries showed more modest increases in the number of films produced. Due to new national film policies in some of these countries, they have begun regular production of films for the first time in their history."

"This analysis has highlighted some unique trends in the global cinema sector. First, there is a tendency for the “global film industry” (dominated by Hollywood productions) to produce sequels, prequels and adaptations (non-original ideas) that are targeted to mass media, children and youth, resulting in a concentration of world production. Second, film production is highly concentrated with 7% of the countries with regular film production making 55% of all feature films globally. India itself produced 20% of all films worldwide. Blockbusters outside of the USA have mainly been USA-produced comedies, breaking records all over the world. National productions or coproductions that are not distributed by Hollywood major studios have had almost no circulation beyond national borders. In the period 2005-2011, world admissions dropped by 12.8%, while box office revenues rose by 27.8% (average ticket price increased by 46%, especially since the 3D boom). Market concentration is still very high; Top 10 countries represented around 75% of world box office and 85% of world admissions. The concentration for admissions slowly increased from 85% to 90% between 2005 and 2011. Similar to patterns in the world macro-economy, the BRIC group (Brazil,the Russian Federation, India and China) is increasing its market share of the world film market (both production and admissions). China is the main star of this story: based on conservative estimates, by early 2020 the Asiatic giant will surpass USA as the main film market in the world. Other regions, like Latin America , have improved their film market indicators, but they are still low (except for Brazil and Mexico) in comparison to other regions. There are many individual countries that had impressive box office growth (21 countries with increases from 102% to 556%), in comparison with admissions rises (10 countries increasing from 100% to 156%). In other words, the world film screen market is losing spectators but increasing revenues–mainly due to increased ticket prices. In the context of many large countries,such as China, the Russian Federation and India,“lacking cinema screens, the development of their cinema infrastructure could give a push to the world film market”(Miller, 2008)."

"The concern that violent video games may promote aggression or reduce empathy in its players is pervasive and given the popularity of these games their psychological impact is an urgent issue for society at large. Contrary to the custom, this topic has also been passionately debated in the scientific literature. One research camp has strongly argued that violent video games increase aggression in its players , whereas the other camp repeatedly concluded that the effects are minimal at best, if not absent. Importantly, it appears that these fundamental inconsistencies cannot be attributed to differences in research methodology since even meta-analyses, with the goal to integrate the results of all prior studies on the topic of aggression caused by video games led to disparate conclusions. These meta-analyses had a strong focus on children, and one of them reported a marginal age effect suggesting that children might be even more susceptible to violent video game effects. At present, almost all experimental studies targeting the effects of violent video games on aggression and/or empathy focussed on the effects of short-term video gameplay. In these studies the duration for which participants were instructed to play the games ranged from 4 min to maximally 2 h (mean = 22 min, median = 15 min, when considering all experimental studies reviewed in two of the recent major meta-analyses in the field) and most frequently the effects of video gaming have been tested directly after gameplay."

"Taken together, the findings of the present study show that an extensive game intervention over the course of 2 months did not reveal any specific changes in aggression, empathy, interpersonal competencies, impulsivity-related constructs, depressivity, anxiety or executive control functions; neither in comparison to an active control group that played a non-violent video game nor to a passive control group. We observed no effects when comparing a baseline and a post-training assessment, nor when focussing on more long-term effects between baseline and a follow-up interval 2 months after the participants stopped training. To our knowledge, the present study employed the most comprehensive test battery spanning a multitude of domains in which changes due to violent video games may have been expected. Therefore the present results provide strong evidence against the frequently debated negative effects of playing violent video games. This debate has mostly been informed by studies showing short-term effects of violent video games when tests were administered immediately after a short playtime of a few minutes; effects that may in large be caused by short-lived priming effects that vanish after minutes. The presented results will therefore help to communicate a more realistic scientific perspective of the real-life effects of violent video gaming. However, future research is needed to demonstrate the absence of effects of violent video gameplay in children."

"Several theoretical perspectives explain how exposure to computer games, especially violent games, can lead to imitative behavior. It is clear why these theories of TV violence might easily be applied in a gaming environment. Perhaps the most comprehensive theory to date is the general aggression model (GAM), which comprehensively integrates central elements from several earlier aggression theories. Included in the model are elements of social cognitive theory (Bandura, 1994), which focuses on the audience member's attention to the modeled behavior, retention of that behavior, ability to imitate, and motivation to imitate the behavior. Furthermore, social cognitive theory concentrates on the model, noting that admired and rewarded models are more likely to be imitated. As such, the theory focuses on both the contextual cues (e.g., whether violence is rewarded) and the cognitive structures that lead to imitation. Script theory (Huesmann, 1986) is also integrated into the general aggression model. Script theory focuses on learned and activated scripts, arguing that we might learn to respond to situations in particular ways based on situations that have been repeatedly modeled for us. Therefore, in a new situation (e.g., a conflict), we might draw on scripts observed in the media, such as those containing violence. Also included in the general aggression model is cognitive-neoassociative priming theory (Berkowitz, 1993; Berkowitz & Heimer, 1989), which draws largely on network models of memory. Given that memory is organized through a network, ideas can prime or active related thoughts. Berkowitz argued that exposure to media violence, especially over long periods of time, could serve to create a rich, intricate memory network of hostility and violence for heavy viewers. The result, according to priming theory, is that exposure to media violence could then readily activate hostility and aggressive thoughts. In addition to cognitive-neoassociative priming theory, Green's affective aggression model (1990 explains that increased in aggression after exposure to media violence could result in hostility and negative affect. Furthermore, Zillmann's (1983) excitation transfer model focuses on the mechanism of physiological arousal as the cause of increases in aggression after exposure to violence."

"The general aggression model also explains that exposure to videogame violence can increase aggressive behavior both in the short and long term by noting that aggression is largely based on existing knowledge structures or existing mental scripts that are created by the process of social learning (Anderson et al., 2004). That is, individuals can learn new skills and information by watching the behaviors of others, especially if those behaviors are rewarded, performed by attractive actors, or do not cause pain or suffering fort the victim of aggression (i.e., sanitized violence). In the short term, both personological and situational input variables can lead to aggressive behavior. Personological variables include personality variables such as aggressive disposition, current states, beliefs, attitudes, and so on. Situational variables are found in the environment surrounding the person and include factors such as aggressive cues (e.g., playing a violent videogame), being provoked, or feeling pain. Both of these inputs can impact the present internal state of the person. For example, aggression may become more likely if an individual has an aggressive disposition and also plays an aggressive videogame. This may lead to feelings of hostility. Then, given the opportunity to retaliate against someone who has insulted the person, for example, that individual may behave more aggressively than someone without those personological or situational factors in place."

"Cantor (1994) has used Piagetian developmental theory in order to explain and predict what images frighten children at different stages of cognitive developmental progress. Wilson and Weiss (1991) have also used Piagetian developmental theory in order to understand children's responses to news media. Kremar and colleagues (Kremar & Cooke, 2001; Kremar & Valkenburg, 1999) have utilized Kohlberg's theories of moral development in order to understand how children of different ages respond to depictions of interpersonal violence in the media. Because Kohlberg argues that judgments about right and wrong are based on a different decision matrix for children of different ages, it makes sense that how children interpret violence, a potentially immoral act, may differ for younger versus older children. For example, children younger than age 5 tend to use the guidance of an authority figure in order to determine between right and wrong or may simply consider the outcome of an action in making such a judgement. Older children, in contrast, may consider the motive of the actor in order to decide whether an act was wrong (Kohlberg, 1984). In summary, child development, whether studied in the context of cognitive development, moral development, or emotional or social development, has provided a solid framework-one that focused on the child more than on the medium-to understand the responses of a group that is qualitatively different from its adult counterparts."

"In their narrative review of the empirical literature, Dill and Dill (1998) concluded that short-term exposure to violent videogames increases aggression. Similarly, Bensley and Van Eenwyk (2001) conclude there is evidence that playing violent videogames can increase short-term aggression in young children. Meta-analyses conducted on the research on violent videogames have also supported an effect of game play on aggression. The first such comprehensive study was conducted by Anderson and Bushman (2001). Across all studies included in their meta-analysis, the authors found that exposure to violent videogames was positively associated with increased levels of aggression. Anderson (2004) recently updated with original meta-analysis and concluded that when only those studies with the soundest methodological approaches were used, results showed even stronger effect sizes, suggesting that methodologically weaker studies actually underestimate the true effects of exposure to volent videogames. Another meta-analysis by Sherry (2001) using 25 studies found evidence for a small effect of videogame play on aggression. However, Sherry also found that effect sizes have increased over time, with more current studies producing stronger effects, presumably due to the greater realism of today's games. Game type was also important, as games classified as human violence or fantasy violence were found to be more strongly related to aggression than sports games."

"I can never forget the first sensations I experienced when it dawned upon me that I had observed something possibly of incalculable consequences to mankind. I felt as though I were present at the birth of a new knowledge or the revelation of a great truth. Even now, at times, I can vividly recall the incident, and see my apparatus as though it were actually before me. My first observations positively terrified me, as there was present in them something mysterious, not to say supernatural, and I was alone in my laboratory at night; but at that time the idea of these disturbances being intelligently controlled signals did not yet present itself to me. The changes I noted were taking place periodically, and with such a clear suggestion of number and order that they were not traceable to any cause then known to me. I was familiar, of course, with such electrical disturbances as are produced by the sun, Aurora Borealis and earth currents, and I was as sure as I could be of any fact that these variations were due to none of these causes. The nature of my experiments precluded the possibility of the changes being produced by atmospheric disturbances, as has been rashly asserted by some. It was some time afterward when the thought flashed upon my mind that the disturbances I had observed might be due to an intelligent control. Although I could not decipher their meaning, it was impossible for me to think of them as having been entirely accidental. The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another. A purpose was behind these electrical signals; and it was with this conviction that I announced to the Red Cross Society, when it asked me to indicate one of the great possible achievements of the next hundred years, that it would probably be the confirmation and interpretation of this planetary challenge to us. Since my return to New York more urgent work has consumed all my attention; but I have never ceased to think of those experiences and of the observations made in Colorado. I am constantly endeavoring to improve and perfect my apparatus, and just as soon as practicable I shall again take up the thread of my investigations at the point where I have been forced to lay it down for a time. -Nikola Tesla"

"In 2006, I hosted a dinner after a screening of An Inconvenient Truth, former vice president Al Gore's seminal documentary on the climate crisis. We went around the table for everyone's reaction to the film's urgent message. When it came to my fifteen-year-old daughter, Mary, she declared with her typical candor: "I'm scared, and I'm angry." Then she added, "Dad, your generation created this problem. You better fix it." . . . As a venture capitalist, my job is to find big opportunities, target big challenges, and invest in big solutions. I was best known for backing companies like Google and Amazon early on. But the environmental crisis dwarfed any challenge I'd ever seen. . . . Eugene Kleiner, the late cofounder of Kleiner Perkins . . . left behind a set of twelve laws that [included the following:] There is a time when panic is the appropriate response. That time had come. . . . My partners and I made climate a top priority. We got serious about investing in clean and sustainable technologies . . . . Our climate investments were [slow] out of the gate, and many of them failed. . . . But with patience and persistence [by 2019] our surviving cleantech investments began to hit one home run after the next. [However, we currently] have no time for a victory lap. . . . Atmospheric carbon already exceeds the upper limit for climate stability. . . . The effects of runaway global warming are already plain to see: devastating hurricanes, biblical flooding, uncontrollable wildfires, killer heat waves, and extreme droughts. . . . I must warn you up front: we're not cutting emissions fast enough to outrun the damage on our doorstep. I said this in 2007, and I say it again today: what we're doing is not nearly enough. Unless we course correct with urgent speed and at a massive scale, we'll be staring at a doomsday scenario. The melting polar ice caps will drown coastal cities. Failed crops will lead to widespread famine. By midcentury, a billion souls worldwide could be climate refugees. . . . Fortunately, we have a powerful ally in this fight: innovation. Over the past fifteen years, prices for solar and wind power have plunged 90 percent. . . . Batteries are expanding the range of electrified vehicles at an ever lower cost. Greater energy efficiency has sharply reduced greenhouse gas emissions. . . . While a good many solutions are in hand, their deployment is nowhere near where it needs to be. We'll need massive investment and robust policy to make these innovations more affordable. We need to scale the ones we have - immediately - and invent the ones we still need. In short, we need both the now and the new."

"The global energy crisis is driving a sharp acceleration in installations of renewable power, with total capacity growth worldwide set to almost double in the next five years, overtaking coal as the largest source of electricity generation along the way and helping keep alive the possibility of limiting global warming to 1.5 °C . . . . Global renewable power capacity is now expected to grow by 2,400 gigawatts (GW) over the 2022-2027 period, an amount equal to the entire power capacity of China today, according to Renewables 2022, the latest edition of the IEA {International Energy Agency}’s annual report on the sector. . . . The amount of renewable power capacity added in Europe in the 2022-27 period is forecast to be twice as high as in the previous five-year period, driven by a combination of energy security concerns and climate ambitions. . . . Beyond Europe, the upward revision in renewable power growth for the next five years is also driven by China, the United States and India, which are all implementing policies and introducing regulatory and market reforms more quickly than previously planned to combat the energy crisis. . . . China is expected to account for almost half of new global renewable power capacity additions over the 2022-2027 period. Meanwhile, the US Inflation Reduction Act has provided new support and long-term visibility for the expansion of renewables in the United States. . . . Utility-scale solar PV [photovoltaics] and onshore wind are the cheapest options for new electricity generation in a significant majority of countries worldwide. Global solar PV capacity is set to almost triple over the 2022-2027 period, surpassing coal and becoming the largest source of power capacity in the world. The report also forecasts an acceleration of installations of solar panels on residential and commercial rooftops . . . . Global wind capacity almost doubles in the forecast period, with offshore projects accounting for one-fifth of the growth. Together, wind and solar will account for over 90% of the renewable power capacity that is added over the next five years. . . . While China remains the dominant player [in photovoltaic supply chains], its share in global manufacturing capacity could decrease from 90% today to 75% by 2027. . . . Total global biofuel demand is set to expand by 22% over the 2022-2027 period. . . . In advanced economies . . . faster growth [in renewable power capacity] would require various regulatory and permitting challenges to be tackled and a more rapid penetration of renewable electricity in the heating and transport sectors. In emerging and developing economies, [faster growth] would mean addressing policy and regulatory uncertainties, weak grid infrastructure and a lack of access to affordable financing that are hampering new projects. . . . Worldwide, the accelerated case requires efforts to resolve supply chain issues, expand grids and deploy more flexibility resources to securely manage larger shares of variable renewables. The accelerated case’s faster renewables growth would move the world closer to a pathway consistent with reaching net zero emissions by 2050, which offers an even chance of limiting global warming to 1.5 °C."

"With global electricity demand set to grow strongly, new technologies {like enhanced geothermal systems and closed-loop geothermal systems} are opening up the massive potential of geothermal energy to provide around-the-clock clean power in almost all countries around the world, according to a new IEA report. The report, The Future of Geothermal Energy, finds that geothermal energy could meet 15% of global electricity demand growth between now and 2050 if project costs continue to decline. This would mean . . . delivering annual output equivalent to the current electricity demand of the United States and India combined. . . . Importantly, geothermal energy can draw upon the expertise of today’s oil and gas industries by using existing drilling techniques and equipment to go deeper under the earth’s surface . . . . Conventional geothermal remains a location-specific, niche technology today with most of the installed capacity in countries that have either volcanic activity or straddle tectonic fault lines . . . . But new technologies are . . . opening up the potential to benefit from it in nearly all countries. . . . [T]he report finds that costs could fall by 80% by 2035 to around $50 per megawatt hour (MWh). This would make geothermal the cheapest source of dispatchable low-emissions electricity on a par with existing hydropower and nuclear installations. . . . If next-generation geothermal grows strongly in the coming years, employment in the overall geothermal sector could increase sixfold to 1 million jobs by 2030 . . . . Up to 80% of the investment required in geothermal involves capacity and skills that are transferrable from existing oil and gas operations. The oil and gas industry can also benefit {because next-generation geothermal can} serve as a hedge against commercial risks related to projected future declines in oil and gas demand. At a time when the digital economy and artificial intelligence applications are growing strongly {and with} next-generation geothermal offering a stable and essentially inexhaustible power source, large technology companies are already signing power purchase agreements with new projects."

"[1] 2023 saw a step change in renewable capacity additions, driven by China’s solar PV market. Global annual renewable capacity additions increased by almost 50% to nearly 510 gigawatts (GW) in 2023, the fastest growth rate in the past two decades. . . . [2] Achieving the COP28 target of tripling global renewable capacity by 2030 hinges on policy implementation. . . . [C]hallenges [that could prevent reaching the tripling goal] fall into four main categories and differ by country: 1) policy uncertainties and delayed policy responses to the new macroeconomic environment; 2) insufficient investment in grid infrastructure preventing faster expansion of renewables; 3) cumbersome administrative barriers and permitting procedures and social acceptance issues; 4) insufficient financing in emerging and developing economies. . . . [3] The global power mix will be transformed by 2028. . . . In 2028, renewable energy sources [are expected to] account for over 42% of global electricity generation, with the share of wind and solar PV doubling to 25%. . . . [4] China is the world’s renewables powerhouse. . . . China’s role is critical in reaching the global goal of tripling renewables because the country is expected to install more than half of the new capacity required globally by 2030. . . . [5] The US, the EU, India and Brazil remain bright spots for onshore wind and solar PV growth. . . . Supportive policy environments and the improving economic attractiveness of solar PV and onshore wind are the primary drivers behind this acceleration. . . . [6] Solar PV prices plummet amid growing supply glut. . . . Despite unprecedented PV manufacturing expansion in the United States and India driven by policy support, China is expected to maintain its 80‑95% share of global supply chains . . . . [7] Onshore wind and solar PV are cheaper than both new and existing fossil fuel plants. . . . Despite the increasing contribution needs for flexibility and reliability to integrate variable renewables, the overall competitiveness of onshore wind and solar PV changes only slightly by 2028 in Europe, China, India and the United States. . . . [8] The new macroeconomic environment presents further challenges that policy makers need to address. . . . Since 2022, central bank base interest rates have increased from below 1% to almost 5%. . . . The implications . . . are manifold . . . . [I]nflation has increased equipment costs . . . [H]igher interest rates are increasing the financing costs of capital-intensive variable renewable technologies. . . . [And] policy has been relatively slow to adjust to the new macroeconomic environment due in part to expectations that cost reductions would continue . . . . [9] The forecast for wind capacity additions is less optimistic outside China, especially for offshore. . . .The wind industry, especially in Europe and North America, is facing challenges due to a combination of ongoing supply chain disruptions, higher costs and long permitting timelines. . . . [10] Faster deployment of variable renewables increases integration and infrastructure challenges. . . . Although European Union interconnections help integrate solar PV and wind generation, grid bottlenecks will pose significant challenges and lead to increased curtailment in many countries as grid expansion cannot keep pace with accelerated installation of variable renewables. . . . [11] Current hydrogen plans and implementation don’t match. . . . We have revised down our forecasts for all regions except China. The main reason is the slow pace of bringing planned projects to final investment decisions due to a lack of off‑takers and the impact of higher prices on production costs. . . . [12] Biofuel deployment is accelerating and diversifying more into renewable diesel and biojet fuel. . . . Emerging economies, led by Brazil, dominate global biofuel expansion . . . . Biofuels remain the dominant pathway for avoiding oil demand in the diesel and jet fuel segments. EVs outpace biofuels in the gasoline segment, especially in the United States, Europe and China. . . . [13] Aligning biofuels with a net zero pathway requires a huge increase in the pace of deployment. . . . Much faster biofuel deployment is possible through new policies and addressing supply chain challenges. [14] Renewable heat accelerates amid high energy prices and policy momentum – but not enough to curb emissions. . . . [The renewable heat acceleration comes] predominantly from the growing reliance on electricity for process heat – notably with the adoption of heat pumps in non‑energy‑intensive industries – and the deployment of electric heat pumps and boilers in buildings, increasingly powered by renewable electricity."

"The world’s demand for electricity is rising at its fastest rate in years, driven by robust economic growth, intense heatwaves and increasing uptake of technologies that run on electricity such as EVs and heat pumps, according to a new report by the IEA. At the same time, renewables continue their rapid ascent, with solar PV on course to set new records. . . . Global electricity demand is forecast to grow by around 4% in 2024 and {will do so} into 2025, with growth around 4% again . . . . {The} share of global electricity supply {generated by renewables is} forecast to rise from 30% in 2023 to 35% in 2025. The amount of electricity generated by renewables worldwide in 2025 is forecast to eclipse the amount generated by coal for the first time. Solar PV alone is expected to meet roughly half of the growth in global electricity demand over 2024 and 2025 - with solar and wind combined meeting as much as three-quarters of the growth. Despite the sharp increases in renewables, global power generation from coal is unlikely to decline this year due to the strong growth in demand, especially in China and India . . . As a result, carbon dioxide (CO2) emissions from the global power sector are plateauing, with a slight increase in 2024 followed by a decline in 2025. …Some of the world’s major economies are registering particularly strong increases in electricity consumption. Demand in India is expected to surge by a massive 8% this year . . . . China is also set to see significant demand growth of more than 6% . . . . After declining in 2023 amid mild weather, electricity demand in the United States is forecast to rebound this year by 3% . . . . By contrast, the European Union will see . . . growth forecast at 1.7% . . . . In many parts of the world, increasing use of air-conditioning will remain a significant driver of electricity demand. Multiple regions faced intense heatwaves . . . . With the rise of artificial intelligence (AI), the electricity demand of data centres is drawing increased attention . . . ."

"The power of custom is enormous, and so gradual will be the change, that man's sense of what is due to himself will be at no time rudely shocked; our bondage will steal upon us noiselessly and by imperceptible approaches; nor will there ever be such a clashing of desires between man and the machines as will lead to an encounter between them. Among themselves the machines will war eternally, but they will still require man as the being through whose agency the struggle will be principally conducted. In point of fact there is no occasion for anxiety about the future happiness of man so long as he continues to be in any way profitable to the machines; he may become the inferior race, but he will be infinitely better off than he is now. Is it not then both absurd and unreasonable to be envious of our benefactors? And should we not be guilty of consummate folly if we were to reject advantages which we cannot obtain otherwise, merely because they involve a greater gain to others than to ourselves? “With those who can argue in this way I have nothing in common. I shrink with as much horror from believing that my race can ever be superseded or surpassed, as I should do from believing that even at the remotest period my ancestors were other than human beings. Could I believe that ten hundred thousand years ago a single one of my ancestors was another kind of being to myself, I should lose all self-respect, and take no further pleasure or interest in life. I have the same feeling with regard to my descendants, and believe it to be one that will be felt so generally that the country will resolve upon putting an immediate stop to all further mechanical progress, and upon destroying all improvements that have been made for the last three hundred years. I would not urge more than this. We may trust ourselves to deal with those that remain, and though I should prefer to have seen the destruction include another two hundred years, I am aware of the necessity for compromising, and would so far sacrifice my own individual convictions as to be content with three hundred. Less than this will be insufficient.”"

"I have grown accustomed to the disrespect expressed by some of the participants for their colleagues in the other disciplines. "Why, Dan," ask the people in artificial intelligence, "do you waste your time conferring with those neuroscientists? They wave their hands about 'information processing' and worry about where it happens, and which neurotransmitters are involved, but they haven't a clue about the computational requirements of higher cognitive functions." "Why," ask the neuroscientists, "do you waste your time on the fantasies of artificial intelligence? They just invent whatever machinery they want, and say unpardonably ignorant things about the brain." The cognitive psychologists, meanwhile, are accused of concocting models with neither biological plausibility nor proven computational powers; the anthropologists wouldn't know a model if they saw one, and the philosophers, as we all know, just take in each other's laundry, warning about confusions they themselves have created, in an arena bereft of both data and empirically testable theories. With so many idiots working on the problem, no wonder consciousness is still a mystery. All these charges are true, and more besides, but I have yet to encounter any idiots. Mostly the theorists I have drawn from strike me as very smart people – even brilliant people, with the arrogance and impatience that often comes with brilliance – but with limited perspectives and agendas, trying to make progress on the hard problems by taking whatever shortcuts they can see, while deploring other people's shortcuts. No one can keep all the problems and details clear, including me, and everyone has to mumble, guess and handwave about large parts of the problem."

"What makes the goal of accuracy so vexing for chatbots is that they operate probabilistically when choosing the next word in a sentence; they aren’t trying to find the light of truth in a murky world. “These models are built to generate text that sounds like what a person would say — that’s the key thing,” Jesse Dodge says. “So they’re definitely not built to be truthful.” I asked Margaret Mitchell, a computer scientist who studied the ethics of A.I. at Google, whether factuality should have been a more fundamental priority for A.I. Mitchell, who has said she was fired from the company for criticizing how it treated colleagues working on bias in A.I. (Google says she was fired for violating the company’s security policies), said that most would find that logical. “This common-sense thing — ‘Shouldn’t we work on making it factual if we’re putting it forward for fact-based applications?’ — well, I think for most people who are not in tech, it’s like, ‘Why is this even a question?’” But, Mitchell said, the priorities at the big companies, now in frenzied competition with one another, are concerned with introducing A.I. products rather than reliability. The road ahead will almost certainly lead to improvements. Mitchell, who now works as the chief ethics scientist at the A.I. company Hugging Face, told me that she foresees A.I. companies’ making gains in accuracy and reducing biased answers by using better data. “The state of the art until now has just been a laissez-faire data approach,” she said. “You just throw everything in, and you’re operating with a mind-set where the more data you have, the more accurate your system will be, as opposed to the higher quality of data you have, the more accurate your system will be.” Jesse Dodge, for his part, points to an idea known as “retrieval,” whereby a chatbot will essentially consult a high-quality source on the web to fact-check an answer in real time. It would even cite precise links, as some A.I.-powered search engines now do. “Without that retrieval element,” Dodge says, “I don’t think there’s a way to solve the hallucination problem.” Otherwise, he says, he doubts that a chatbot answer can gain factual parity with Wikipedia or the Encyclopaedia Britannica."

"Even if conflicts like this don’t impede the advance of A.I., it might be stymied in other ways. At the end of May, several A.I. researchers collaborated on a paper that examined whether new A.I. systems could be developed from knowledge generated by existing A.I. models, rather than by human-generated databases. They discovered a systemic breakdown — a failure they called “model collapse.” The authors saw that using data from an A.I. to train new versions of A.I.s leads to chaos. Synthetic data, they wrote, ends up “polluting the training set of the next generation of models; being trained on polluted data, they then misperceive reality.” The lesson here is that it will prove challenging to build new models from old models. And with chat-bots, Ilia Shumailov, an Oxford University researcher and the paper’s primary author, told me, the downward spiral looks similar. Without human data to train on, Shumailov said, “your language model starts being completely oblivious to what you ask it to solve, and it starts just talking in circles about whatever it wants, as if it went into this madman mode.” Wouldn’t a plug-in from, say, Wikipedia, avert that problem, I asked? It could, Shumailov said. But if in the future Wikipedia were to become clogged with articles generated by A.I., the same cycle — essentially, the computer feeding on content it created itself — would be perpetuated."

"Barack Obama: My general observation is that it has been seeping into our lives in all sorts of ways, and we just don’t notice; and part of the reason is because the way we think about AI is colored by popular culture. There’s a distinction, which is probably familiar to a lot of your readers, between generalized AI and specialized AI. In science fiction, what you hear about is generalized AI, right? Computers start getting smarter than we are and eventually conclude that we’re not all that useful, and then either they’re drugging us to keep us fat and happy or we’re in the Matrix. My impression, based on talking to my top science advisers, is that we’re still a reasonably long way away from that. It’s worth thinking about because it stretches our imaginations and gets us thinking about the issues of choice and free will that actually do have some significant applications for specialized AI, which is about using algorithms and computers to figure out increasingly complex tasks. We’ve been seeing specialized AI in every aspect of our lives, from medicine and transportation to how electricity is distributed, and it promises to create a vastly more productive and efficient economy. If properly harnessed, it can generate enormous prosperity and opportunity. But it also has some downsides that we’re gonna have to figure out in terms of not eliminating jobs. It could increase inequality. It could suppress wages."

"First, in dealing with those nations that break rules and laws, I believe that we must develop alternatives to violence that are tough enough to actually change behavior – for if we want a lasting peace, then the words of the international community must mean something. Those regimes that break the rules must be held accountable. Sanctions must exact a real price. Intransigence must be met with increased pressure – and such pressure exists only when the world stands together as one. One urgent example is the effort to prevent the spread of nuclear weapons, and to seek a world without them. In the middle of the last century, nations agreed to be bound by a treaty whose bargain is clear: All will have access to peaceful nuclear power; those without nuclear weapons will forsake them; and those with nuclear weapons will work towards disarmament. I am committed to upholding this treaty. It is a centerpiece of my foreign policy. And I’m working with President Medvedev to reduce America and Russia’s nuclear stockpiles. But it is also incumbent upon all of us to insist that nations like Iran and North Korea do not game the system. Those who claim to respect international law cannot avert their eyes when those laws are flouted. Those who care for their own security cannot ignore the danger of an arms race in the Middle East or East Asia. Those who seek peace cannot stand idly by as nations arm themselves for nuclear war. The same principle applies to those who violate international laws by brutalizing their own people. When there is genocide in Darfur, systematic rape in Congo, repression in Burma – there must be consequences. Yes, there will be engagement; yes, there will be diplomacy – but there must be consequences when those things fail. And the closer we stand together, the less likely we will be faced with the choice between armed intervention and complicity in oppression."

"At 162 feet long, this rocket, the Soyuz-FG, is noticeably smaller than the assembled space shuttle, but it's still a daunting colossus, a building-size object that will, we hope, leave the ground, with us riding on top of it, at twenty-five times the speed of sound. Its navy gray sheet metal, adorned with low-tech rivets, is unbeautiful but somehow comforting in its utility. The Soyuz-FG is the grandchild of the Soviet R-7, the world's first intercontinental ballistic missile. The R-7 was designed during the Cold War for launching nuclear weapons at American targets, and I can't help remembering how as a child I was aware that New York City, and my suburb of West Orange, New Jersey, would have certainly been among the first targets to be instantly vaporized by a Soviet attack. Today, I'm standing inside their formerly secret facility, discussing with two Russians our plans to trust one another with our lives while riding to space on this converted weapon. Gennady, Misha and I all served in our militaries before being chosen to fly in space, and though it's something we never talk about, we all know we could have been ordered to kill one another. Now we are taking part in the largest peaceful international collaboration in history. When people ask whether the space station is worth the expense, this is something I always point out. What is it worth to see two former bitter enemies transform their weapons into transport for exploration and the pursuit of scientific knowledge? . . . This is impossible to put a dollar figure on, but to me it's one of the things that makes this project worth the expense, even worth risking our lives."

"For years after World War II, both the United States and the Soviet Union had been trying to perfect a long-range missile capable of carrying nuclear warheads. Building on the successes of Nazi Germany in developing the V-1 and V-2 rockets that pummeled Great Britain during the last months of World War II, both American and Russian scientists raced to improve the range and accuracy of such missiles. (Both nations relied heavily on captured German scientists in their efforts.) In July 1957, the United States seemed to win the race when the Atlas, an ICBM with a speed of up to 20,000 miles an hour and an effective range of 5,000 miles, was ready for testing. The test, however, was a disaster. The missile rose only about 5,000 feet into the air, tumbled, and plunged to earth. Just a month later, the Soviets claimed success by announcing that their own ICBM had been tested, had “covered a huge distance in a brief time,” and “landed in the target area.” No details were given in the Russian announcement and some commentators in the United States doubted that the ICBM test had been as successful as claimed. Nevertheless, the Soviet possession of this “ultimate weapon,” coupled with recent successful test by the Russians of atomic and hydrogen bombs, raised concerns in America. If the Soviets did indeed perfect their ICBM, no part of the United States would be completely safe from possible atomic attack. Less than two months later, the Soviets sent the satellite Sputnik into space."

"Fred Friendly, the head of CBS news, understood that satellites, with instant transmissions, would eventually become accessible from most places in the world at any time of day and that this awkward invention would one day change the nature not only of television news, but of news itself. In 1965, he wanted a live satellite broadcast from somewhere in the world on the Cronkite evening news, which came on at 7:00 P.M. New York City time. Looking for a place in the world that could send to Early Bird at seven New York City time, he found Berlin, which had been a major story for several years. Schorr was placed at the Berlin Wall, always a good visual, and it was—live! Schorr’s entreaties that nothing was happening at the Wall in the middle of the night were useless. He was missing the point. The point was that it would be live. “So indeed, I stood there,” Schorr recounted. “This is the wall, behind here is where East Germany is, and all. And then, because we were there with lights on, you would hear dogs barking. Dogs started to bark and ‘you would hear dogs barking sometimes chasing some poor East German who was trying to escape. I don’t know that that is happening right now’—a lot of crap! But it was live.” CBS even talked a court in Germany that was trying an accused Nazi into holding a session after midnight so that it could be carried live rather than filming the normal day session and playing it that night. The age of live television news had begun."

"Suppose a clothing manufacturer learns of a machine that will make men’s and women’s overcoats for half as much labor as previously. He installs the machines and drops half his labor force. This looks at first glance like a clear loss of employment. But the machine itself required labor to make it; so here, as one offset, are jobs that would not otherwise have existed. The manufacturer, how ever, would have adopted the machine only if it had either made better suits for half as much labor, or had made the same kind of suits at a smaller cost. If we assume the latter, we cannot assume that the amount of labor to make the machines was as great in terms of pay rolls as the amount of labor that the clothing manufacturer hopes to save in the long run by adopting the machine; otherwise there would have been no economy, and he would not have adopted it. So there is still a net loss of employment to be accounted for. But we should at least keep in mind the real possibility that even the first effect of the introduction of labor-saving machinery may be to increase employment on net balance; because it is usually only in the long run that the clothing manufacturer expects to save money by adopting the machine: it may take several years for the machine to “pay for itself.” After the machine has produced economies sufficient to offset its cost, the clothing manufacturer has more profits than before. (We shall assume that he merely sells his coats for the same price as his competitors, and makes no effort to undersell them.) At this point, it may seem, labor has suffered a net loss of employment, while it is only the manufacturer, the capitalist, who has gained. But it is precisely out of these extra profits that the subsequent social gains must come. The manufacturer must use these extra profits in at least one of three ways, and possibly he will use part of them in all three: (1) he will use the extra profits to expand his operations by buying more machines to make more coats; or (2) he will invest the extra profits in some other industry; or (3) he will spend the extra profits on increasing his own consumption. Whichever of these three courses he takes, he will increase employment."

At first he used the explosive force of gunpowder, and later the use of the expansive force of steam, to raise the piston, and then by removing the fire to cause it to fall again. He made no further use of this principle. Savery discovered that the sudden condensation of steam made a vacuum that he utilized to draw up water. His pumps were actually used to drain mines, but were never satisfactory. They had to be placed within the mine to be drained, not over forty feet from the bottom, and then could be used to force up water an additional height of perhaps 100 feet. Beyond this the process must be repeated. It will be noticed that the water to be forced came into direct contact with the steam, which was contained in a solid vessel. In addition tremendous pressures were necessary: as high as 1,200 pounds per square inch were secured, and with the materials for construction at hand frequent and disastrous explosions were the result. Newcomen used Papin's cylinder and piston, and Savery's principle of the condensation of steam to produce a vacuum. But unlike Papin he used the expansive force of steam to do his work, and unlike Savery he used a cylinder and piston actuated by alternate expansion and condensation of steam to transform heat into mechanical motion."

"At first [Newcomen] made a double cylinder, using the space between for condensing water. This was not very satisfactory. The vacuum was secured very slowly and imperfectly. In 1711 they attempted to erect an engine for draining a mine, but failed. The next year they succeeded... but it was slow and ineffective. To operate it, required two men and a boy. The boy's work was to alternately open and close the valves to the condensing water and to the boiler. One day the engine made two or three motions quickly and powerfully. Newcomen immediately examined the cylinder and found a small hole, through which a small jet from the water that was on top of the piston to make it steam tight, was spurting into the cylinder. He appreciated the significance... [and] dispensed with the outer water jacket and injected the water for condensation, through a small pipe in the bottom of the cylinder. It... increased the speed of the engine from eight to fifteen strokes a minute, besides getting the advantage of a good vacuum. In 1713 a pump was erected in , and the boy who was hired to open and shut the valves, in an effort to make his work easier, rigged up a contrivance of strings and levers that operated the valves from the motion of the working beam over head. This made the engine automatic and marked another stage in its evolution. This boy, Humphrey Potter... This valve motion was afterward improved by in 1718. This engine... continued to be until the days of Watt..."

"If the Steam Engine be the most powerful instrument in the hands of man, to alter the face of the physical world, it operates, at the same time, as a powerful moral lever in forwarding the great cause of civilization. ...If ...we are now met to consider of placing a monument to the memory of Mr. Watt beside the monuments of those who fell in the splendid victories of the last war, let it not be said that there is no connexion between the services of this modest and unobtrusive benefactor of his country, and the triumphs of the heroes which those monuments are destined to commemorate. ...It has been often said, that many of the great discoveries in science are due to accident; but it was well remarked by [Humphry Davy]... that this cannot be the case with the principal discovery of Mr. Watt. ... Again, it has frequently happened that those philosophers, who have made brilliant and useful discoveries... have only been able to turn their discoveries to the purpose of averting evils threatening, and often destroying, the precarious tenure of human existence. Thus Franklin disarmed the thunderbolt, and conducted it innocuous through our buildings, and close to our fire-sides—thus Jenner stripped a loathsome and destructive disease of its virulence, and rendered it harmless of devastation—thus [Davy]... sent the safety lamp into our mines to save... their useful inhabitants from the awful explosion of the fire damp. But the discovery of Mr. Watt went further: he subdued and regulated the most terrific power in the universe,—that power which, by the joint operation of pressure and heat, probably produces those tremendous convulsions of the earth, which in a moment subvert whole cities, and almost change the face of the inhabited globe. This apparently ungovernable power Mr. Watt reduced to a state of such perfect organization and discipline... that it may now be safely manœuvred and brought into irresistible action—irresistible, but still regulated, measured, and ascertained—or lulled into the most complete and secure repose, at the will of man, and under the guidance of his feeble hand. Thus one man directs it into the bowels of the earth, to tear asunder its very elements, and bring to light its hidden treasures; another places it upon the surface of the waters, to control the winds of heaven, to stem the tides, to check the currents, and defy the waves of the ocean; a third, perhaps and a fourth, are destined to apply this mighty power to other purposes, still unthought of and unsuspected, but leading to consequences, possibly not less important than those which it has already produced. ... those benefits, conferred by Mr. Watt on the whole civilized world, have been most experienced by his own country, which owes a tribute of national gratitude to a man, who has thus honoured her by his genius, and promoted her well being by his discoveries."

"About the year 1761, or 1762, I tried some experiments on the force of steam in a Papin's digester, and formed a species of steam-engine by fixing upon it a syringe, one-third of an inch diameter, with a solid piston, and furnished also with a cock to admit the steam from the digester, or shut it off at pleasure, as well as to open a communication from the inside of the syringe to the open air, by which the steam contained in the syringe might escape. When the communication between the digester and syringe was opened, the steam entered the syringe, and by its action upon the piston raised a considerable weight (15 lbs.) with which it was loaded. When this was raised as high as was thought proper, the communication with the digester was shut, and that with the atmosphere opened; the steam then made its escape, and the weight descended. The operations were repeated, and, though in this experiment the cock was turned by hand, it was easy to see how it could be done by the machine itself, and to make it work with perfect regularity. But I soon relinquished the idea of constructing an engine upon its principle, from being sensible it would be liable to some of the objections against Savery's engine, viz., the danger of bursting the boiler, and the difficulty of making the joints tight, and also that a great part of the power of the steam would be lost, because no vacuum was formed to assist the descent of the piston. I, however, described this engine in the fourth article of the specification of my patent of 1769; and again in the specification of another patent in the year 1784, together with a mode of applying it to the moving of wheel-carriages."

"Beginning with the 1984 presidential campaign, the neoconservative Reagan administration and the Christian Right accelerated their use of television and video imagery to capture political discourse- and power. Along with a new series of "Ron and Nancy" commercials, the Reverend Pat Robertson's "700 Club" (a kind of right-wing talk show), and a resurgence of Good versus Evil kiddie cartoons, American television and video viewers were bombarded with the newest "pro life" propaganda piece, The Silent Scream. The Silent Scream marked a dramatic shift in the contest over abortion imagery. With formidable cunning, it translated the still and by-now stale images of fetus as "baby" into real-time video, thus (1) giving those images an immediate interface with the electronic media; (2) transforming antiabortion rhetoric from a mainly religious/mystical to a medical/technological mode; and (3) bringing the fetal image "to life. "On major network television the fetus rose to instant stardom, as The Silent Scream and its impresario, Dr. Bernard Nathanson, were aired at least five different times in one month, and one well-known reporter, holding up a fetus in a jar before 10 million viewers, announced: "This thing being aborted, this potential person, sure looks like a baby! This statement is more than just propaganda; it encapsulates the "politics of style" dominating late capitalist culture, transforming "surface impressions" into the "whole message." The cult of appearances not only is the defining characteristic of national politics in the United States, but it is also nourished by the language and techniques of photo/video imagery. Aware of cultural trends, the current leadership of the antiabortion movement has made a conscious strategic shift from religious discourses and authorities to medicotechnical ones, in its effort to win over the courts, the legislatures, and popular hearts and minds. But the vehicle for this shift is not organized medicine directly but mass culture and its diffusion into reproductive technology through the video display terminal."

"Recently, icdn's role as a willing accomplice in the mass murders of Gypsies — and indeed, the larger question of its Swiss operation — has come back to haunt the technology company. Big Blue has refused to answer the charges since the first simultaneous disclosures in 40 countries on February 11, 2001, that IBM knowingly systemized Hitler's persecution and extermination of Europe's Jews, directly from New York and through its subsidiaries in Europe coordinated through the Swiss office. But on June 22, a Swiss appellate Court ruled that a compensation suit filed by the Gypsy (Roma) (Roma) International Recognition and Compensation Action could proceed. "The precision, speed and reliability of IBM's machines," the Swiss judge ruled, "especially related to the censuses of the German population and racial biology by the Nazis, were praised in the publications of Dehomag itself, the branch of respondent IBM. It does not thus seem unreasonable to deduce that IBM's technical assistance facilitated the tasks of the Nazis in the commission of their crimes against humanity, acts also involving accountancy and classification by IBM machines and utilized in the concentration camps themselves." The judge's ruling pointedly added: "In view of the preceding, IBM's complicity with material and intellectual assistance in the criminal acts of the Nazis during the Second World War by means of its Geneva establishment does not appear to be ruled out, as there is a great deal of evidence indicating that the Geneva establishment was aware that it was aiding and supporting these acts.""

"Glass... helped to alter the very concept of self. In a small way, glass had been used for mirrors by the Romans; but the background was a dark one, and the image was no more plain than... the polished metal surface. By the sixteenth century, even before the invention of plate glass that followed a hundred years later, the mechanical surface of the glass had been improved to such an extent that, by coating it with a silver amalgam, an excellent mirror could be created. ...For perhaps the first time, except for reflections in the water and in the dull surfaces of metal mirrors, it was possible to find an image that corresponded accurately to what others saw. ...The use of the mirror signalled the beginning of introspective biography in the modern style... The self in the mirror corresponds to the physical world that was brought to light by natural science in the same epoch: it was the self in abstracto... the more accurate the physical instrument, the more sufficient the light on it, the more relentlessly does it show the effects of age, disease, disappointment, slyness, covetousness, weakness... quite as clearly as health, joy and confidence. Indeed, when one is completely whole and at one with the world one does not need the mirror: it is in the period of psychic disintegration that the individual... turns to the lonely image to see what in fact is there and what he can hold on to; and it was in the period of cultural disintegration that men began to hold the mirror up to outer nature."

"Outwards from London, Glasgow, Amsterdam and Hamburg there radiated the lines - shipping lines, railway lines, telegraph lines - that were the sinews of Western imperial power. Regular steamships connected the great commercial centres to every corner of the globe. They criss-crossed the oceans; they plied its great lakes; they chugged up and down its navigable rivers. At the ports where they loaded and unloaded their passengers and cargoes, there were railway stations, and from these emanated the second great network of the Victorian age: the iron rails, along which ran rhythmically, in accordance with scrupulously detailed timetables, a clunking cavalcade of steam trains. A third network, of copper and rubber rather than iron, enabled the rapid telegraphic communication of orders of all kinds: orders to be obeyed by imperial functionaries, orders to be filled by overseas merchants - even holy orders could use the telegraph to communicate with the thousands of missionaries earnestly disseminating West European creeds and ancillary beneficial knowledge to the heathen. These networks bound the world together as never before, seeming to 'annihilate distance' and thereby creating truly global markets for commodities, manufactures, labour and capital. In turn, it was these markets that peopled the prairies of the American Mid-West and the steppe of Siberia, grew rubber in Malaya and tea in Ceylon, bred sheep in Queensland and cattle in the pampas, dug diamonds from the pipes of Kimberley and gold from the rich seams of the Rand."

"There are three different primary energy-supply system classes which may be used to implement the hydrogen economy, namely, fossil fuels (coal, petroleum, natural gas, and as yet largely unused supplies such as shale oil, oil from tar sands, natural gas from geo-pressured locations, etc.), nuclear reactors including fission reactors and breeders or fusion nuclear reactors over the very long term, and renewable energy sources (including hydroelectric power systems, wind-energy systems, ocean thermal energy conversion systems, geothermal resources, and a host of direct solar energy-conversion systems including biomass production, photovoltaic energy conversion, solar thermal systems, etc.). Examination of present costs of hydrogen production by any of these means shows that the hydrogen economy favored by people searching for a non-polluting gaseous or liquid energy carrier will not be developed without new discoveries or innovations. Hydrogen may become an important market entry in a world with most of the electricity generated in nuclear fission or breeder reactors when high-temperature waste heat is used to dissociate water in chemical cycles or new inventions and innovations lead to low-cost hydrogen production by applying as yet uneconomical renewable solar techniques that are suitable for large-scale production such as direct water photolysis with suitably tailored band gaps on semiconductors or low-cost electricity supplies generated on ocean-based platforms using temperature differences in the tropical seas."

"In July of 1934 an editorial in The Commonweal, a semi-official organ of the Catholic church, declared that the “muck merchants” of Hollywood, that “fortress of filth” that had been destroying the moral fiber of the American people, had finally been brought to its knees by the Catholic church and its Legion of Decency. In less than a year the church had recruited millions of Americans of all religious denominations to pledge not to attend “immoral” movies. With a national depression already threatening Hollywood’s financial stability, movie czar Will Hays, head of the Motion Picture Producers and Distributors of American (MPPDA), accepted the terms of surrender dictated by the church and its legions. The truce struck between Hays and the Most Reverend John T. McNicholas, Archbishop of Cincinnnati, and written and negotiated by Martin Quigley, publisher of “The Motion Picture Herald”, signaled a turning point in a 30-year battle among religious leaders, women’s groups, civic organizations, municipal and state censorship boards, and the motion picture industry over the content of Hollywood films. The victory took the form of a new agency inside the MPPDA, the industry's trade association. The Catholics demanded that Hays create Production Code Administration (PCA) to enforce the censorship code adopted by the industry in 1930. The code, written by a Catholic priest, had not, in the opinion of the church, been enforced. The church demanded, and Hays agreed, that a staunch lay Catholic, namely Joseph I. Breen, would head the PCA and interpret the code. To guarantee that Breen would have enforcement powers, the agreement forced every studio to submit scripts to the PCA before production. The studios agreed that no production would begin without script approval and that no film would be distributed with a PCA seal of approval. The MPPDA was given power to levy a $25,000 fine against any violator. But that was not all. The church demanded that Hollywood permanently withdraw from circulation films it viewed as “immoral” and that local theater owners be empowered to cancel any film currently in circulation if they judged it to be “immoral.”"

"Prior to the advent of artificial lighting, the sun was the primary source of light. When the sun sets today, however, one is hard-pressed to find darkness—illumination from light-emitting diodes (LEDs), and incandescent, fluorescent, and xenon-arc sources (among others) provide indoor and outdoor illumination. The effects of exposure to this seemingly unnatural technological adaptation are starting to become evident, with several studies indicating undesirable associations between exposure to artificial light at night and both reduced sleep quality and diminished alertness during the day. A relatively recent concern is the excessive near-field exposure to handheld and other electronic light-emitting devices. Estimates from large population surveys in developed countries indicate that 35% of people born between the years of 1965 and 1996 spend at least 9 h/day on digital devices, such as smartphones, tablets, or computers, and a recent report indicates that the average American spends 10 h and 39 min viewing screens. Such intense use of these devices has been found to have undesirable effects not only on sleep quality and alertness during waking hours, but also on parameters of physical health (e.g., neck and eye strain, eye fatigue, headache;) and cognitive performance (e.g., poor inhibitory control;). The prevalence of complaints associated with excessive use of computers and other digital devices is so great that the common ocular and physical effects have been collectively termed “Computer Vision Syndrome” (CVS)."

"The history of science may be described as the breaking down, and the crumbling away, of artificially constructed barriers. All the great men of science have been famous wall-breakers. ...It is worthy to remark that the central conception of the alchemists ...was the unity of natural phenomena. ...[T]heir arguments would be somewhat as follows—Plants grow from seeds ...animals become larger, stronger, and more complete ...the plant may well be called more perfect than the seed, and the full grown animal more perfect than the immature ...both plants and animals grow, come to their prime, and decay; and there are degrees of perfection in the animal and vegetable worlds. Now—we may suppose the argument of the alchemist... minerals and metals and all inanimate things should grow, and change, from less perfect to more perfect forms; as there are degrees of perfectness and dignity in among all living things, so... among all things; some metals disappear in acrid liquids, and... are... easily worn away, they are readily melted and burnt to ; but some other metals are not swallowed up by corrosive liquids, nor... worn away with ease, nor readily changed in fire; there are evidently noble and base metals, perfect and imperfect metals; and as the less perfect seed... produces the more perfect plant... rendered yet more perfect by cultivation, so the imperfect metals change slowly into... more perfect, and this... can be hastened by man's art and devices. ...[L]iving things are more perfect that inanimate things ...[M]uch more must changes from immature to mature forms be constantly proceeding from dead things like minerals and metals ...[I]t is probable that the plasticity of the minerals and metals will be greater ...hence ...it will be a comparatively easy thing to grow a noble metal like gold from ignoble metals like and copper, although it is impossible to change one kind of animal into another or one sort of plant into another ... A vague conception of the unity of nature... led to little accurate knowledge..; all that could be done was to perform a vast number of inaccurate and incomplete experiments, and to state the results in loose and slipshod language of the vague but sonorous hypothesis which prompted the experiments. And so although the hypothesis postulated the unity of nature there was no unity in the experimental results... collected to support the hypothesis. ...A man who sets out to discover what is must endeavour to put aside all his notions of what ought to be; it is only when he has gained a solid foundation of verified and accurate facts that he may venture to make a definite guess concerning the cause ...but unless he makes clearly stated guesses ...scientific hypotheses—he will remain a mere collector of half facts ..."

"RECOMMENDATION 6: Ferrocement in Disaster Relief. After fires, floods, droughts, and earthquakes... [t]ransportation is often disrupted... Supplies of bulky conventional building materials may be stranded outside the disaster area, whereas the basic ingredients of ferrocement may be available on the site or easily transported. The versatility of ferrocement also reduces logistical supply problems: wire mesh, cement, sand, and water can be substituted for the metal used for roofing, woods or plastic for shelters and clinics, asphalt for helipads, steel for bridges, and so on. Moreover, most ferrocement structures, though built for an emergency, will last long after the emergency is over. ...[F]errocement could be used at a disaster site for many purposes: Transport facilities, from simple boats to barges, docks, marinas, helipads, and simple floating bridges or short footbridges as well as road repairs. ...Food-storage facilities, quickly designed to local needs and quickly built, to preserve emergency food supplies. ...Emergency shelters such as, for example, the quonset type of roof, which is easy to erect and highly efficient. ..Public health facilities, such as latrines and clinics, built with ferrocement roofs and stucco-type walls of the same wire mesh and mortar. ...[C]adres of ferrocement workers could be trained in emergency applications and the supervision of local laborers at the disaster site."

"a surrogate activity is an activity that is directed toward an artificial goal that the individual pursues for the sake of the “fulfillment” that he gets from pursuing the goal, not because he needs to attain the goal itself. For instance, there is no practical motive for building enormous muscles, hitting a little ball into a hole or acquiring a complete series of postage stamps. Yet many people in our society devote themselves with passion to bodybuilding, golf or stamp-collecting. Some people are more “other-directed” than others, and therefore will more readily attach importance to a surrogate activity simply because the people around them treat it as important or because society tells them it is important. That is why some people get very serious about essentially trivial activities such as sports, or bridge, or chess, or arcane scholarly pursuits, whereas others who are more clear-sighted never see these things as anything but the surrogate activities that they are, and consequently never attach enough importance to them to satisfy their need for the power process in that way. It only remains to point out that in many cases a person’s way of earning a living is also a surrogate activity. Not a PURE surrogate activity, since part of the motive for the activity is to gain the physical necessities and (for some people) social status and the luxuries that advertising makes them want. But many people put into their work far more effort than is necessary to earn whatever money and status they require, and this extra effort constitutes a surrogate activity."

"The system does not and cannot exist to satisfy human needs. Instead, it is human behavior that has to be modified to fit the needs of the system. This has nothing to do with the political or social ideology that may pretend to guide the technological system. It is the fault of technology, because the system is guided not by ideology but by technical necessity. Of course the system does satisfy many human needs, but generally speaking it does this only to the extend that it is to the advantage of the system to do it. It is the needs of the system that are paramount, not those of the human being. For example, the system provides people with food because the system couldn’t function if everyone starved; it attends to people’s psychological needs whenever it can CONVENIENTLY do so, because it couldn’t function if too many people became depressed or rebellious. But the system, for good, solid, practical reasons, must exert constant pressure on people to mold their behavior to the needs of the system. To much waste accumulating? The government, the media, the educational system, environmentalists, everyone inundates us with a mass of propaganda about recycling. Need more technical personnel? A chorus of voices exhorts kids to study science. No one stops to ask whether it is inhumane to force adolescents to spend the bulk of their time studying subjects most of them hate. When skilled workers are put out of a job by technical advances and have to undergo “retraining,” no one asks whether it is humiliating for them to be pushed around in this way."

"suppose the system survives the crisis of the next several decades. By that time it will have to have solved, or at least brought under control, the principal problems that confront it, in particular that of “socializing” human beings; that is, making people sufficiently docile so that their behavior no longer threatens the system. That being accomplished, it does not appear that there would be any further obstacle to the development of technology, and it would presumably advance toward its logical conclusion, which is complete control over everything on Earth, including human beings and all other important organisms. The system may become a unitary, monolithic organization, or it may be more or less fragmented and consist of a number of organizations coexisting in a relationship that includes elements of both cooperation and competition, just as today the government, the corporations and other large organizations both cooperate and compete with one another. Human freedom mostly will have vanished, because individuals and small groups will be impotent vis-a-vis large organizations armed with supertechnology and an arsenal of advanced psychological and biological tools for manipulating human beings, besides instruments of surveillance and physical coercion. Only a small number of people will have any real power, and even these probably will have only very limited freedom, because their behavior too will be regulated; just as today our politicians and corporation executives can retain their positions of power only as long as their behavior remains within certain fairly narrow limits."

"it is possible that human control over the machines may be retained. in that case the average man may have control over certain private machines of his own, such as his car or his personal computer, but control over large systems of machines will be in the hands of a tiny elite — just as it is today, but with two differences. Due to improved techniques the elite will have greater control over the masses; and because human work will no longer be necessary the masses will be superfluous, a useless burden on the system. If the elite is ruthless they may simply decide to exterminate the mass of humanity. If they are humane they may use propaganda or other psychological or biological techniques to reduce the birth rate until the mass of humanity becomes extinct, leaving the world to the elite. Or, if the elite consists of soft-hearted liberals, they may decide to play the role of good shepherds to the rest of the human race. They will see to it that everyone’s physical needs are satisfied, that all children are raised under psychologically hygienic conditions, that everyone has a wholesome hobby to keep him busy, and that anyone who may become dissatisfied undergoes “treatment” to cure his “problem.” Of course, life will be so purposeless that people will have to be biologically or psychologically engineered either to remove their need for the power process or to make them “sublimate” their drive for power into some harmless hobby. These engineered human beings may be happy in such a society, but they most certainly will not be free. They will have been reduced to the status of domestic animals."

"Massachusetts in 1835 had a population of some 660,940, 81 percent rural, overwhelmingly preindustrial and native born. Its citizens were used to considerable personal freedom. Whether teamsters, farmers or artisans, they were all accustomed to setting their own schedules, and the nature of their work made them physically independent of each other.... Individual problems, sins or even crimes, were not generally cause for wider social concern...."But the impact of the twin movements to the city and to the factory, both just gathering force in 1835, had a progressive effect on personal behavior throughout the 19th century and into the 20th. The factory demanded regularity of behavior, a life governed by obedience to the rhythms of clock and calendar, the demands of foreman and supervisor. In the city or town, the needs of living in closely packed neighborhoods inhibited many actions previously unobjectionable. Both blue- and white-collar employees in larger establishments were mutually dependent on their fellows; as one man’s work fit into another’s, so one man’s business was no longer his own. “The results of the new organization of life and work were apparent by 1900, when some 76 percent of the 2,805,346 inhabitants of Massachusetts were classified as urbanites. Much violent or irregular behavior which had been tolerable in a casual, independent society was no longer acceptable in the more formalized, cooperative atmosphere of the later period."
