My company HQ is in SF still, not sure how much longer. I get to visit downtown fairly frequently. SF is so bad today that people just leave their car windows open lest some thief accidently believe they had the audacity to lock their cars. Many major retailers that I was used to seeing downtown have left. The criminals and homeless run the show in SF. Really sad to see how far it has gone in such a short period of time. I'm not sure why X is leaving, but X is just another company in a long list of companies. Often they'll take with them the people who worked there, then there's just that many fewer functional citizens as a percentage in the city. When does it become a vicious cycle?
