I don't live in the US but I visit sometimes in Bay Area for business. The most amazing cultural thing in SF that blew my mind was the existence of startup scene as a cultural phenomenon, subculture and lifestyle. I'm not completely sure if this is cultural misunderstanding and I am missing something, but it seemed like for every real young entrepreneur there was ten dreamers who were just hanging in the scene for vibes. Dropping out from collage "to startup" but spending their time just hanging out with the group of people with the same subculture. It seemed like pitching a startup was a hobby and maybe phase in life just like sabbatical year. I find it utterly fascinating. I have no idea if it has negative effects or if it's completely positive phenomenon. Clearly there is lots of young energy in the air.
