If you think that's SV you're probably not the ambitious personality type I was referring to, while also being unaware of what's getting the focus these days in SV (which is most certainly AI/ deep learning).

I've lived in more cities (3 months+) than most in this forum being a perennial digital nomad (And I don't know why people keep citing Tokyo - the culture is not pro entrepreneurship for young people at all, there is no real concept of a coworking spaces, etc. I did however meet a lot of white techies from SF so maybe that's why people are getting that impression!). It's a certain type of ambition/ personality that's encouraged here, for better or worse.
