We don't have civilian super-sonic flight or manned space flight anymore. I'd say in some ways we're slipping backwards as far as technological progress is concerned. Progress in energy technology is particularly pathetic. Nuclear energy was discovered in the 30s and no significant new source of power has been developed since (Solar isn't significant).
- jeffreymcmanus 15y agoIf you're on the international space station, solar is indeed significant.
- wyclif 15y agoIsn't it possible that manned space flight could be considered "slipping backward"? Unmanned space flight is supposed to be an advance because it doesn't put human life at risk, IOW it's an efficiency.
