Technological progress, unlike war or Wall Street style high finance, is not a zero-sum game, and that makes all the difference. The Promethean force of technology is today, and always has been, the force that has rescued humanity from its worst problems just when it seemed impossible to avert civilizational collapse. With every single technological advance, from the invention of writing to the invention of television, those who have failed to appreciate the non-zero-sum nature of technological evolution have prophesied doom and been proven wrong. Every time, they have made some version of the argument: this time it is different, and been proven wrong.
