Not true in the slightest. There was little crime, you could walk everywhere safely, day or night, and the food was still incredible, and cheap.
Major parts of the city were on a roadmap towards revitalization before dotcom was ever a thing. Yerba Buena Gardens was competed in 1993, for example. No disruption required.
> Until the first dotcom boom the city was in decline, or at least that's how the story goes.
It’s the exact opposite. The city was undergoing major revitalization before the dotcom era. The first dotcom boom brought major gentrification, and with it, people who didn’t care for the values and culture of the city.
