I was musing over something, though. We have creeping Orwellian things like face recognition and the policing of chat histories. But some of this is private, as in, not done by the state. Even when done by the state, it isn't in most places to prop up the regime and prevent dissent. It's big brother mechanisms without a Big Brother. I speculate that it's genuinely motivated by preventing disorder, because (is this true?) over the last couple of decades people have got more disorderly in petty ways to do with thieving and harassing and scamming one another. Then the people don't like it, and so the people politically demand heavy-handed policing of the people.
