We're always so concerned with machines recognizing us, but what about other people? If I live in a small village, the owner of the general store will surely remember my face just like an ML-laden camera or POS system. We get creeped out when machines suggest things related to our past behavior, but love it when the bartender already knows what we like. People who remember you can spread rumors just like your data can be sold to another company.
I'm not trying to say that privacy doesn't matter at all, of course. I'm just wondering how much things have actually changed, privacy-wise.
