Yeah sure let's move to the South Bay and live in the 12th circle of Hell, a.k.a., the worst abomination of city planning known to North America. San Jose used to be a city on the upswing but after the riots and COVID it has the feeling of a shell of a city that is being kept alive by the nice infrastructure they built there a short while ago. Sunnyvale is peak suburbia -- endless tracts of suburban homes and strip malls with not a single good piece of public transit infrastructure to speak of (VTA has terrible station planning and trains from CalTrain comes every few millennia). Cupertino is basically a walled community where only people with incomes of over $500k gain access. Milpitas is a city that essentially doesn't exist, not even the people who I know live there admit its existence. Los Altos is like Cupertino but everyone has a Stanford education and is a next-level evolved NIMBY, and Los Gatos is kinda like that but with more wine and pretentiousness. Saratoga and Campbell are so deep inside the suburban critical mass that it takes ~30 minutes to drive to anything of note, and you'll be blasting your AC while you do so because the coastal fog burns off very quickly in those parts. Outside of the aforementioned tech conferences there aren't many things to do in the Bay Area -- people who live there have been drawn in by either the good schools or jobs.
... all that being said, I have lived in the Bay Area for a long time and do not intend to leave anytime soon. There aren't many other places in the world that can be called hubs of biotech, software and semiconductors all at the same time. Many parts of the South Bay are S-tier in terms of safety while maintaining the same price point as SF, so if you prioritize safety over having a life outside the confines of your computer terminal you return to after your 8-6 job, then the South Bay is actually pretty good. If you want to be able to hit the beach after a night of raving and clubbing preceded by 5-star dining and zuck-surfing on the Bay, while being willfully ignorant about the constant risk of a homeless man jumping out of the bushes at you, then SF is your best bet.
