I'm not saying that a lot of great stuff doesn't come out of California/SV (just like Apple, for whom the 'reality distortion field' thing was first coined, also produces great products). The casualness with which you suppose that California alone is producing more innovation the entire rest of the country suggests that you're overwhelmingly focused on a very, very specific definition of 'innovation'.
The places where innovation comes from are going to be places that believe in the future, are open to experimentation and risk, and reason from first principles instead of cargo-cultism. It just seems like California (and SV in particular) has an above-average amount of these things.
There is no "California mindset" just like there's no "Wall Street mindset" in New York. You're just being sectionalist.
