I lived in the future that they were talking about in the ride, but we didn't have progress anymore. We’d outgrown progress. What we had was change. Things changed whenever anyone wanted to change them: design and launch a fleet of wumpuses, or figure out a way to put an emotional antenna in your head, or create a fleet of killer robots, or invent immortality, or gengineer your goats to give silk. Just do it. It'll catch on, or it won't. Maybe it'll catch itself on. Then the world is…different. Then someone else changes it.The status quo doesn't protect itself, it needs defending if it's going to stay put. The problem is that technology gives more of an advantage to an attacker than to a defender. A defender needs to mount a perfect defense. An attacker needs to find one hole in the defense. So once technology gets going, anything can be knocked down—evil doesn't stand—but nothing much can be erected in its place.
