I wouldn't buy AR glasses, but also feel powerless to prevent myself from being in the reticule of those who do. When you think about what LLMs and facial recognition allow, we're entering a new conception of the public sphere and personal space/human dignity. I think it goes beyond the traditional notion of "privacy" or "public spaces" and closer to questions about moral rights over your likeness and aggregated personal information.
For instance, what if they invented "X-Ray Spex" like there used to be advertised in the back of comic books, that let you see through people's clothes. Do you have an "expectation of privacy" on a subway train against someone seeing you nude, if the technology exists to do it? I feel like similar cultural standards should apply when it comes to triangulating details about your identity from surreptitious recording devices.
