Your first two examples are just as easy and legal with a phone. Nobody watches all their windows all the time nor watches every other beach goer. The third example is already illegal and if a doctor or nurse is already committed to illegally recording patients, what’s stopping them from just hiding cameras in their rooms?

I’m not saying it’s good that people can unknowingly be recorded at any time, but it is already true before the glasses. There’s already cameras everywhere and hidden cameras are already easy to get your hands on. The glasses don’t enable anything new as far as cameras go, they’re actually just way more expensive than any basic hidden cameras you can already buy.

I think people will want the glasses for their ease of use and people will get used to there being cameras everywhere because they already are.
