In my lifetime we have:
outpassed Star Trek communicators, when did you ever see Spok playing tetris?
ended decades of cold war nuclear terror (true it's been replaced but...)
created a GLOBAL culture that thinks freedom of information is a pretty good thing (despots and totalitarian regimes aside it's still a fairly widespread belief and growing)
created simulated worlds not just for scientific research but for friggin entertainment!
invented devices that have mapped the activity of the brain during orgasm
I am awestruck when I think about it all, and excited by what else can be in store.
