I would be happy if all tech left the city. It used to be a hipster village of social non challants and detected alternative social movements. A shining, hairy, culty, body odor having, punk rock city on a hill.
The tech takeover ruined the city and contributed directly to the epidemic levels of homelessness seen because it made the city effectively so expensive non millionaires can't survive there. Most long time san Francisco families ended up moving out.
Take all the rest of tech with you please Mr. Musk. Make San Francisco an affordable city again.
