On the other hand, if San Francisco zoning mostly deflects away non-techies who add to San Francisco congestion without adding much to its tech-centre synergies, then San Francisco's regulations may be reinforcing its status as technological leader.
That leaves technology as the saving grace. Maybe we invent really good holodecks, which make it much less critical to actually be in San Francisco. Maybe we invent teleportation, laws of physics be damned. Maybe we simply come up with better ways to build and design cities, which minimise the real or perceived downsides to residents of new building.
