Actually useful AR needs cameras, of course, so the technology has legitimate use cases, but you'd have to be a real asshole to wear them to a bar, or a restaurant, etc. Maybe we mandate that the glasses have to have a base station dongle, and if they're more than 10 feet from the dongle, recording doesn't work without incredibly obvious annoying lights indicating that recording is on?

A cultural convention that lets people make honest mistakes, but turn it off when someone says "hey, you're recording" seems like a good solution. Just need to make it easily visible and obvious to others - you can run around in public with a big news camera on your shoulder or a tripod and you usually won't get hassled. It's just the idea of being covertly recorded, even while in public, that gets creepy.
