Just to point out few facts: New York City isn't a capital of anything, nor is San Francisco. VCs are in the South Bay, not in San Francisco.
If you need to brush up on the history of new york and san francisco as 'financial capitals'.
SF may be a financial capital to some degree, but your comment about VC is still off: they're not based in the city, and they didn't take much interest in companies in the city at all until recently.
