Simply walking from a hotel to Moscone was very stressful. There were no cops but tons of private security to manage a horde of zombie like addicts and mentally ill homeless.
SF will come back because it is beautiful and the weather is great… it won’t become Detroit. Detroit only had lake transport going for it and grew despite harsh winters.
It won’t happen until there are tons of cops, the homeless dissipate (hopefully to somewhere they can be cared for) and then and only then, people feel safe.
If the Game Developers Conference leaves in the meantime, I will be very happy. I don’t want to go back.
