Ask HN: If not San Francisco then where?

Here on HN is not that unusual that a post about how dystropian or just how a very bad living option is San Francisco has become over the last decade. I was planning to move there from Barcelona over the course of the next year, but i'm seriously starting to think it might not be a so good option. As many others (especially living in EU) I have idealized San Francisco as the place to be if you are a techy with an entrepreneurial actitude. The place in which ideas flows and interesting conversation are happening, where artists and creativiy are perfectly combined with the technolgy and innovators.

So if not there anymore, then where?
