Yes, of course the Silicon Valley attracts CompSci professionals from all over the world, but the SI doesn't employ them. Strange people you say? I've never been to San Francisco, but I've heard that it's considered home to weirdos of every possible kind. Maybe that's the people the SI panders to?

All people who like SI are by definition out of the mainstream, but not all people out of the mainstream are whom SI 'panders' to.

It's not like Peter Thiel doesn't know how to use the Internet or can't afford flying.

And yet...

Facebook, for instance, was located in Massachusetts and only moved to the Silicon Valley in 2011.

How wasteful of them. Don't they know they can just use the Internet to do this thing called 'social networking'? There's no reason for them to be in Silicon Valley. Hopefully their shareholders will do something about that.
