While I don't buy the "facebook is just games and noise" stuff, I do think we should be focusing a bit more in things like clean tech, space missions, etc. Why does almost everybody want to go work for facebook instead of tesla or any other innovative company not primarily focused in "web" development? And yeah, the big equity bucks, but I think those could be moving towards other tech fields too...
