"From the start, the cyborg was more than just another technical project; it was a kind of scientific and military daydream. The possibility of escaping its annoying bodily limitations led a generation that grew up on Superman and Captain America to throw the full weight of its grown-up R&D budget into achieving a real-life superpower. By the mid-1960s, cyborgs were big business, with millions of US Air Force dollars finding their way into projects to build exoskeletons, master-slave robot arms, biofeedback devices, and expert systems. For all the big bucks and high seriousness, the prevailing impression left by old cyborg technical papers is of a rather expensive kind of science fiction. Time and again, scientific reasoning melts into metaphysical speculation about evolution, human boundaries, and even the possibility of what Clynes and Kline call "a new and larger dimension for man's spirit." The cyborg was always as much a creature of scientific imagination as of scientific fact. It wasn't only the military that was captivated by the possibilities of the cyborg. The dream of improving human capabilities through selective breeding had long been a staple of the darker side of Western medical literature. Now there was the possibility of making better humans by augmenting them with artificial devices. Insulin drips had been used to regulate the metabolisms of diabetics since the 1920s. A heart-lung machine was used to control the blood circulation of an 18-year-old girl during an operation in 1953. A 43-year-old man received the first heart pacemaker implant in 1958. By the 1970s, the idea of an augmented human had entered the mainstream. Steve Austin, The Six Million Dollar Man, and his cohort Jaime Sommers, The Bionic Woman (with bionic limbs and a super-sensitive bionic ear), were popular heroes, their custom superpowers bought off the shelf like a digital watch. The cyborg had grown from a lecture-room fantasy into the stuff of prime-time TV."
