The relative power structure won't meaningfully shift. Levels will just change. The guy whose 1% of this pie is meaningful today may find that it is unsustainable tomorrow. The gal who lives richly on her 10% of the pie may have to tighten a belt or two tomorrow, but it's unlikely to become be existential. More tangibly, city services will pull away from non-core areas, projects and services.

I would argue that despite budget increases we have not seen an appreciable increase in operating service levels across the board - from transit to infrastructure to homeless outreach and everything in between. Hard to believe with a $9B (yes, billion) budget. [1]

(Yes, there are capital expenditures happening that are quite visible but do we really need an extension of the slow T-line to Fishermans Wharf?)

Well, I think the ones that were around before the tech influx will certainly be able to ride out slower times better than the restaurants/services that have come up as a direct result of the influx of tech folk.

Because that was before, obviously. Too much of the city relies on the tech economy now - the restaurants, the lyft/uber drivers, the building contractors, the dog walkers, the private school teachers.

But it transitioned towards a reliance on tech before now, there's nothing to suggest it cannot transition away to something else.

It certainly can and will. But not quickly, and with lot of suffering in the interim.

Biotech? Genentech will still be in South SF.
