I’ve always wondered why those guys attracted the crew-cut, law-and-order stereotype when the next wave of techies, the computer hackers, seem to lean the opposite way, toward anarchism of various kinds. (Mostly the silly kind, but that’s another argument.) Here is Rick Prelinger throwing some preliminary light on it. I hope someone is pursuing this further.
