Yeah but were still moving slower than a lot of futurists thought. Part of it is because socialism and the nationalism that really drives socialism has become taboo. Just look at how fast the Germans and soviets progressed when they decided they wanted to be a superpower.
during war, all resources went to that. people worked with urgency. we're just chilling now.
PLUS, I have to think that all the REALLY cool shit is being invented in secret, so as to not give these advantages to other nations. If a dude writes the next 'killer app' in his garage, and can make $100k selling it on Apple one download at a time... or the govt offers him a cool ten million bucks, and they use it for their own purposes, hey, why not take the paycheck?
I'd bet if some natural event caused earth to suddenly suck bad, we'd see crazy fast strides in progress for moving to mars, moon, or just a rotating space station.
