Funny how for all the talk about diversity that goes here on HN and on the West Coast, you guys still don't get that it is perfectly okay to not want to be Silicon Valley.
In my opinion, one of the best essays from PG is "Cities and Ambition"[1]. As much as I'm enjoying my time here in Berlin, I still have the feeling that Berlin still doesn't know what to do when it grows up. Much of the hype here is actually the Kreuzberg types who are suffering from some Peter Pan syndrome, and have absolute zero ambition. Yet, even that is better than "if we don't have a plan, let's just mimic San Francisco".
There is no need to turn everywhere into San Francisco. If an European wants to assimilate SV culture, by all means let him/her go to damn Silicon Valley. But Berlin can and should do something else.
