Seriously though, that city is SO dirty and smelly. The public infrastructure is not only bad and falling apart, but politics is sufficiently broken that very little is likely to be done about it. (Same for housing and homelessness: politics is completely broken, don't expect much to improve in this department.)

And yes, it's a huge techie bubble. In a bad way - most people there are completely detached from any "normal life" perspective. But then again, the same can be said for those in politics in SF.
