What I find amusing is how Silicon Valley's hubris grows inversely with its achievements (and everybody mentions Tesla and SpaceX, but they're clear outliers): Back when people built Intel and all the way through Google, they knew they were advancing technology -- and changing the world through technology -- but that's pretty much where their aspirations ended. Now when people build Snapchat, there's talk of changing the world's currency and seceding from the US, as if Uber and Groupon were the missing pieces to figuring out whatever there was left to understanding how the world works, and now SV can take over.

Obviously, I'm exaggerating. People have always built toys, and it's always hard to understand what's important and what isn't. But the culture -- or religion, if we wish -- around computer technology is new (or at least at an expansionary stage). I think there's more of a political[1] change in SV than a technological one.
