Two-sided markets have virtuous-cycle network effects, yes. DARPA made Silicon Valley, but Stanford and UC Berkeley — and nearby communities that evolved to become basically playgrounds for the students of them — kept it going. Entrepreneurs came (or stayed) to capture the supply of smart and bored college-aged intellectual labor; and VCs came (or stayed) because of all the entrepreneurs. But that doesn't mean that seed-stage companies don't move to (or stay in) the Bay Area these days primarily because of the VCs, rather than because of the talent. Talent is free to move anywhere it likes — especially these days. An entrepreneur will find just as many potential employees for their startup in literally any college city. But tech VCs (and especially ex-tech-entrepreneur angel investors) will, despite having a presence in many places, mostly still live and spend their free time in the Bay Area. And so you'll be much more likely to have your name on their lips if you're showing up at local events they attend, bumping into them at restaurants, meeting them on the golf course, etc. Let me put it this way: every Canadian seed-stage startup I know of, has their CEO regularly fly to the Bay — even if they're located on the east coast of Canada! — to rub shoulders with the Sand Hill VCs, in hopes that they'll get more attention there.
