"Maybe you just can't protect people from certain specialized types of folly with any sane amount of regulation, and the correct response is to give up on the high social costs of inadequately protecting people from themselves under certain circumstances."
"Litmus test: If you can't describe Ricardo's Law of Comparative Advantage and explain why people find it counterintuitive, you don't know enough about economics to direct any criticism or praise at "capitalism" because you don't know what other people are referring to when they use that word."
"I am tempted to say that a doctorate in AI would be negatively useful, but I am not one to hold someone’s reckless youth against them – just because you acquired a doctorate in AI doesn’t mean you should be permanently disqualified."
"There's a standard Internet phenomenon (I generalize) of a Sneer Club of people who enjoy getting together and picking on designated targets. Sneer Clubs (I expect) attract people with high Dark Triad characteristics, which is (I suspect) where Asshole Internet Atheists come from - if you get a club together for the purpose of sneering at religious people, it doesn't matter that God doesn't actually exist, the club attracts psychologically f'd-up people. Bullies, in a word, people who are powerfully reinforced by getting in what feels like good hits on Designated Targets, in the company of others doing the same and congratulating each other on it."
"There was a conference one time on: "What are we going to do about the looming risk of AI disaster?" … And what came out of that conference was OpenAI, which was basically the worst possible way of doing anything. Like, "This is not a problem of, 'Oh no, what if secret elites get AI', it's that nobody knows how to build the thing." … So, like, "Let's open up everything! Let's accelerate everything!" It was like ChatGPT's blind version of throwing the ideals at a place where they were exactly the wrong ideals to solve the problem. … And that was it. That was me in 2015 going, "Oh. So this is what humanity will elect to do. We will not rise above. We will not have more grace, not even here, at the very end." So that is when I did my crying late at night, and then picked myself up and fought and fought and fought until I had run out all the avenues that I seem to have the capability to do."
"You turned into a cat! A SMALL cat! You violated Conservation of Energy! That's not just an arbitrary rule, it's implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get FTL signalling! And cats are COMPLICATED! A human mind can't just visualise a whole cat's anatomy and, and all the cat biochemistry, and what about the neurology? How can you go on thinking using a cat-sized brain?"
"And someday when the descendants of humanity have spread from star to star, they won't tell the children about the history of Ancient Earth until they're old enough to bear it; and when they learn they'll weep to hear that such a thing as Death had ever once existed!"
"Lies propagate, that’s what I’m saying. You’ve got to tell more lies to cover them up, lie about every fact that’s connected to the first lie. And if you kept on lying, and you kept on trying to cover it up, sooner or later you’d even have to start lying about the general laws of thought. Like, someone is selling you some kind of alternative medicine that doesn’t work, and any double-blind experimental study will confirm that it doesn’t work. So if someone wants to go on defending the lie, they’ve got to get you to disbelieve in the experimental method. Like, the experimental method is just for merely scientific kinds of medicine, not amazing alternative medicine like theirs. Or a good and virtuous person should believe as strongly as they can, no matter what the evidence says. Or truth doesn’t exist and there’s no such thing as objective reality. A lot of common wisdom like that isn’t just mistaken, it’s anti-epistemology, it’s systematically wrong. Every rule of rationality that tells you how to find the truth, there’s someone out there who needs you to believe the opposite. If you once tell a lie, the truth is ever after your enemy; and there’s a lot of people out there telling lies."
"Many boys and girls are heroes in their dreams," Dumbledore said quietly. He did not look at any of the other girls, only at her. "Fewer in the waking world. Many have stood their ground and faced the darkness when it comes for them. Fewer come for the darkness and force it to face them. It is a hard life, sometimes lonely, often short. I have told none to refuse that calling, but neither would I wish to increase their number."
"When you are older, you will learn that the first and foremost thing which any ordinary person does is nothing."
"Do not flinch from experiences that might destroy your beliefs. The thought you cannot think controls you more than thoughts you speak aloud. Submit yourself to ordeals and test yourself in fire. Relinquish the emotion which rests upon a mistaken belief, and seek to feel fully that emotion which fits the facts. If the iron approaches your face, and you believe it is hot, and it is cool, the Way opposes your fear. If the iron approaches your face, and you believe it is cool, and it is hot, the Way opposes your calm. Evaluate your beliefs first and then arrive at your emotions. Let yourself say: “If the iron is hot, I desire to believe it is hot, and if it is cool, I desire to believe it is cool.”"
"To confess your fallibility and then do nothing about it is not humble; it is boasting of your modesty."
"In the universe where everything works the way it common-sensically ought to, everything about the study of Artificial General Intelligence is driven by the one overwhelming fact of the indescribably huge effects: initial conditions and unfolding patterns whose consequences will resound for as long as causal chains continue out of Earth, until all the stars and galaxies in the night sky have burned down to cold iron, and maybe long afterward, or forever into infinity if the true laws of physics should happen to permit that. To deliberately thrust your mortal brain onto that stage, as it plays out on ancient Earth the first root of life, is an act so far beyond "audacity" as to set the word on fire, an act which can only be excused by the terrifying knowledge that the empty skies offer no higher authority."
"I have sometimes thought that all professional lectures on rationality should be delivered while wearing a clown suit, to prevent the audience from confusing seriousness with solemnity."
"It would actually be quite surprisingly helpful for increasing the percentage of people who will participate meaningfully in saving the planet, if there were some reliably-working standard explanation for why physics and logic together have enough room to contain morality."
"Declaring yourself to be operating by "Crocker's Rules" means that other people are allowed to optimize their messages for information, not for being nice to you. Crocker's Rules means that you have accepted full responsibility for the operation of your own mind — if you're offended, it's your fault. Anyone is allowed to call you a moron and claim to be doing you a favor. (Which, in point of fact, they would be. One of the big problems with this culture is that everyone's afraid to tell you you're wrong, or they think they have to dance around it.) Two people using Crocker's Rules should be able to communicate all relevant information in the minimum amount of time, without paraphrasing or social formatting. Obviously, don't declare yourself to be operating by Crocker's Rules unless you have that kind of mental discipline. Note that Crocker's Rules does not mean you can insult people; it means that other people don't have to worry about whether they are insulting you. Crocker's Rules are a discipline, not a privilege. Furthermore, taking advantage of Crocker's Rules does not imply reciprocity. How could it? Crocker's Rules are something you do for yourself, to maximize information received — not something you grit your teeth over and do as a favor."
"If you declare Crocker's Rules, other people don't need to worry about being tactful to you. (You still need to worry about being tactful to them — Crocker's Rules only work one way.)"
"Crocker's Rules didn't give you the right to say anything offensive, but other people could say potentially offensive things to you, and it was your responsibility not to be offended. This was surprisingly hard to explain to people; many people would read the careful explanation and hear, "Crocker's Rules mean you can say offensive things to other people.""
"The AI does not hate you, nor does it love you, but you are made out of atoms which it can use for something else."
"People go funny in the head when talking about politics. The evolutionary reasons for this are so obvious as to be worth belaboring: In the ancestral environment, politics was a matter of life and death. And sex, and wealth, and allies, and reputation... When, today, you get into an argument about whether "we" ought to raise the minimum wage, you're executing adaptations for an ancestral environment where being on the wrong side of the argument could get you killed... Politics is an extension of war by other means. Arguments are soldiers. Once you know which side you're on, you must support all arguments of that side, and attack all arguments that appear to favor the enemy side; otherwise it's like stabbing your soldiers in the back — providing aid and comfort to the enemy."
"Ever since I adopted the rule of "That which can be destroyed by the truth should be," I've also come to realize "That which the truth nourishes should thrive." When something good happens, I am happy, and there is no confusion in my mind about whether it is rational for me to be happy. When something terrible happens, I do not flee my sadness by searching for fake consolations and false silver linings. I visualize the past and future of humankind, the tens of billions of deaths over our history, the misery and fear, the search for answers, the trembling hands reaching upward out of so much blood, what we could become someday when we make the stars our cities, all that darkness and all that light — I know that I can never truly understand it, and I haven't the words to say."
"Your strength as a rationalist is your ability to be more confused by fiction than by reality. If you are equally good at explaining any outcome, you have zero knowledge."
"But ignorance exists in the map, not in the territory. If I am ignorant about a phenomenon, that is a fact about my own state of mind, not a fact about the phenomenon itself. A phenomenon can seem mysterious to some particular person. There are no phenomena which are mysterious of themselves. To worship a phenomenon because it seems so wonderfully mysterious, is to worship your own ignorance."
"Between hindsight bias, fake causality, positive bias, anchoring/priming, et cetera et cetera, and above all the dreaded confirmation bias, once an idea gets into your head, it's probably going to stay there."
"If people got hit on the head by a baseball bat every week, pretty soon they would invent reasons why getting hit on the head with a baseball bat was a good thing."
"The strength of a theory is not what it allows, but what it prohibits; if you can invent an equally persuasive explanation for any outcome, you have zero knowledge."
"The police officer who puts their life on the line with no superpowers, no X-Ray vision, no super-strength, no ability to fly, and above all no invulnerability to bullets, reveals far greater virtue than Superman — who is only a mere superhero."
"Lonely dissent doesn't feel like going to school dressed in black. It feels like going to school wearing a clown suit."
"Science has heroes, but no gods. The great Names are not our superiors, or even our rivals, they are passed milestones on our road; and the most important milestone is the hero yet to come."
"The human brain cannot release enough neurotransmitters to feel emotion a thousand times as strong as the grief of one funeral. A prospective risk going from 10,000,000 deaths to 100,000,000 deaths does not multiply by ten the strength of our determination to stop it. It adds one more zero on paper for our eyes to glaze over."
"People cling to their intuitions, I think, not so much because they believe their cognitive algorithms are perfectly reliable, but because they can't see their intuitions as the way their cognitive algorithms happen to look from the inside. And so everything you try to say about how the native cognitive algorithm goes astray, ends up being contrasted to their direct perception of the Way Things Really Are—and discarded as obviously wrong."
"Mystery exists in the mind, not in reality. If I am ignorant about a phenomenon, that is a fact about my state of mind, not a fact about the phenomenon itself. All the more so, if it seems like no possible answer can exist: Confusion exists in the map, not in the territory. Unanswerable questions do not mark places where magic enters the universe. They mark places where your mind runs skew to reality."
"Many humans look at nature from an aesthetic perspective and think in terms of biodiversity and the health of ecosystems, but forget that the animals that inhabit these ecosystems are individuals and have their own needs. Disease, starvation, predation, ostracism, and sexual frustration are endemic in so-called healthy ecosystems. The great taboo in the animal rights movement is that most suffering is due to natural causes. Any proposal for remedying this situation is bound to sound utopian, but my dream is that one day the sun will rise on Earth and all sentient creatures will greet the new day with joy."
"Since we cannot completely eliminate existential risk — at any moment, we might be tossed into the dustbin of cosmic history by the advancing front of a vacuum phase transition triggered in some remote galaxy a billion years ago — the use of maximin in the present context would entail choosing the action that has the greatest benefit under the assumption of impending extinction. Maximin thus implies that we ought all to start partying as if there were no tomorrow. That implication, while perhaps tempting, is implausible."
"It is possible that efforts to contemplate some risk area—say, existential risk—will do more harm than good. One might suppose that thinking about a topic should be entirely harmless, but this is not necessarily so. If one gets a good idea, one will be tempted to share it; and in so doing one might create an information hazard. Still, one likes to believe that, on balance, investigations into existential risks and most other risk areas will tend to reduce rather than increase the risks of their subject matter."
"Aggregative consequentialist theories are threatened by infinitarian paralysis: they seem to imply that if the world is canonically infinite then it is always ethically indifferent what we do. In particular, they would imply that it is ethically indifferent whether we cause another holocaust or prevent one from occurring. If any non-contradictory normative implication is a reductio ad absurdum, this one is."
"In this book, I try to understand the challenge presented by the prospect of superintelligence, and how we might best respond. This is quite possibly the most important and most daunting challenge humanity has ever faced. And—whether we succeed or fail—it is probably the last challenge we will ever face."
"Observers in earlier epochs might have found it equally preposterous to suppose that the world economy would one day be doubling several times within a single lifespan. Yet that is the extraordinary condition we now take to be ordinary."
"Far from being the smartest possible biological species, we are probably better thought of as the stupidest possible biological species capable of starting a technological civilization - a niche we filled because we got there first, not because we are in any sense optimally adapted to it."
"The cognitive functioning of a human brain depends on a delicate orchestration of many factors, especially during the critical stages of embryo development—and it is much more likely that this self-organizing structure, to be enhanced, needs to be carefully balanced, tuned, and cultivated rather than simply flooded with some extraneous potion."
"The gap between a dumb and a clever person may appear large from an anthropocentric perspective, yet in a less parochial view the two have nearly indistinguishable minds."
"Perhaps it is a sign of civilizational progress that the very idea of threatening a nuclear first strike today seems borderline silly or morally obscene."
"[A]ssuming that the observable universe is void of extraterrestrial civilizations, then what hangs in the balance is at least 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 human lives (though the true number is probably larger). If we represent all the happiness experienced during one entire such life with a single teardrop of joy, then the happiness of these souls could fill and refill the Earth’s oceans every second, and keep doing so for a hundred billion billion millennia. It is really important that we make sure these truly are tears of joy."
"Our demise may instead result from the habitat destruction that ensues when the AI begins massive global construction projects using nanotech factories and assemblers—construction projects which quickly, perhaps within days or weeks, tile all of the Earth’s surface with solar panels, nuclear reactors, supercomputing facilities with protruding cooling towers, space rocket launchers, or other installations whereby the AI intends to maximize the long-term cumulative realization of its values. Human brains, if they contain information relevant to the AI’s goals, could be disassembled and scanned, and the extracted data transferred to some more efficient and secure storage format."
"Nature might be a great experimentalist, but one who would never pass muster with an ethics review board – contravening the Helsinki Declaration and every norm of moral decency, left, right, and center."
"Solving the value-loading problem is a research challenge worthy of some of the next generation’s best mathematical talent. We cannot postpone confronting this problem until the AI has developed enough reason to easily understand our intentions."
"Even a single missed crucial consideration could vitiate our most valiant efforts or render them as actively harmful as those of a soldier who is fighting on the wrong side. The search for crucial considerations (which must explore normative as well as descriptive issues) will often require crisscrossing the boundaries between different academic disciplines and other fields of knowledge. As there is no established methodology for how to go about this kind of research, difficult original thinking is necessary."
"Before the prospect of an intelligence explosion, we humans are like small children playing with a bomb. Such is the mismatch between the power of our plaything and the immaturity of our conduct. Superintelligence is a challenge for which we are not ready now and will not be ready for a long time. We have little idea when the detonation will occur, though if we hold the device to our ear we can hear a faint ticking sound."
"In this situation, any feeling of gee-wiz exhilaration would be out of place. Consternation and fear would be closer to the mark; but the most appropriate attitude may be a bitter determination to be as competent as we can, much as if we were preparing for a difficult exam that will either realize our dreams or obliterate them."
"The universe is cold. Fun is the fire that melts the blocks of hardship and creates a bubbling celebration of life. It is the birth right of every creature, a right no less sacred for having been trampled on since the beginning of time."
