Another point on diversity: It's never going to happen to the extent that people want so long as most of the jobs are in Silicon Valley. For many women and minorities and older men (with children), it is difficult to make that move, away from their families. We can't pretend like this isn't a factor. I recently moved to Austin from south Florida and my last company had a very high Hispanic ratio, because it was located in south Florida, where the local population ratio is quite high. I knew many talented developers who couldn't or wouldn't make the move to one of the tech hubs because family. Without spreading out tech jobs over more of the country, you'll never see great representation.
