"The world doesn't just contain optimists and pessimists, and wise and unwise technology users. It contains enemies of civilization as well. And knowledge is impartial. It can be used for good or evil. But the enemies of civilization all necessarily have one thing in common. They are wrong. And so they fear error correction and truth. And that's why they resist changes in their ideas, which makes them less creative and slower to innovate. So our defense against the existential danger from malevolent uses of technology, the only defense, is speed. The good guys must use their only advantage to stay ahead."
