Whole categories of crime disappeared. Women and elderly feel safe to walk the streets at night. No one locks their bike anymore in Chongqing.
I care about privacy, but I think we should be smart enough to work out a way to get some of those benefits without going full 1984. For example by having surveillance that can only be queried by an AI with very strong guard rails.
Admittedly, I live in a country with very strong democratic institutions, and I trust we would take action the moment something gets abused or surveillance overreaches. I would probably feel differently living elsewhere.
