Yeah, AR glasses are what will actually be the Next Smartphone, as far as rapidly attaining ubiquity. If they can fix the bulkiness and battery life issues, anyway. And sure, decent chance that'll involve tethering the glasses to some kind of watch where the actual brains and long-range radios live. Or to a smartphone or tablet that you can leave in a pocket or bag all the time (why wear a watch when the AR glasses could just paint a fake one on your wrist?)
But won't people feel uncomfortable being seen with AR glasses, at least for the next few years? They would have to be completely transparent, no impediment to eye contact, very small and fashionable, and so incredibly useful people would be willing to deal with any judgemental glares they got.
Depends what kind of form factor they can get them to. I've got a pair of these, and they look close enough to regular Ray-Bans that nobody realizes there's cameras on them: https://www.ray-ban.com/usa/ray-ban-stories
Smartphones drew the same judgmental glares for a few years. If you were holding them up to use them, people'd think you were recording and would be irritated or upset. If you were recording, they're really be unhappy with you. People talking on or looking at cell phones in public at all were usually coded as "asshole" in basically all media in the 90s and 00s, and that pretty much reflected popular opinion.
By the early 20-teens, though, all that was just normal and everyone was doing it.
