I'm struggling to find what this has to do with San Francisco? Are you saying SF has been taken over by hipsters and is no longer recognizable as it once were?
While the general validity and the degree to which this writer's experience is shared by others can certainly be debated (which is the reason I tabled it in the first place), the fact that there are strong parallels cannot be contested.
The agents and parties affected in the two settings, London and S.F., could indeed be different. Nonetheless, the theme remains the same.
