I graduated college in the late 00s, and this was already considered a trend then. Airbnb, Dropbox, and Reddit were famously based in SF; while companies from the Google-Facebook era centered in the South Bay. There was a sense that young people didn't want to be in the socially-disconnected, car-dependent suburbs, so companies would have an easier time retaining talent in The City (SF).
