"But for a variety of reasons, the momentum has been in SF's favor as the world's dominant technology hub."
I know this is ancient history, but I keep having to remind folks that the fetish for locating tech companies in SF didn't start until the late 1990s. Then it crashed, and didn't pick up again until the mid/late 'aughts.
Viewed dispassionately, the "momentum" of SF as a technology hub looks more like a fad that happens at the peak of VC consumer investment cycles.
