EDIT: Wanted to add that I'm not really a Silicon Valley hater. Silicon Valley did a lot to make the web what it is today, starting with companies like Netscape and Sun and followed by all the dot com and Web 2.0 powerhouses.
I laugh sometimes at the popularity of things like transhumanism around the Valley. I hear a lot of talk like that, but see little action. Trying to get people to click ads is not going to enhance longevity or intelligence. Most of that work is going on elsewhere, such as at major medical institutes and universities.
It's where the money is. More deals get done on Sand Hill Road than anywhere else. But, it was never where things got invented. The transistor was invented in New Jersey and Shockley set up shop in silicon valley because land was so cheap.
