With Google glasses, it was this strange contraption over one eye, so it was easy to shun or shame them into taking it off when at a conference or in a public bathroom (saw it happen many times).

Problem with these are that the wearer can claim they're prescription, even though there's a camera and mic on them. And there are tons of stickers and covers you can buy online to hide the little recording indicator.

There were also stories that these would soon autorecord/stream everything, and use AI to transcribe what was said and identify anyone encountered. Presumably so you could later go back and review something that you missed.

What we have are essentially millions of portable Flock cameras with infinite storage and personal ID built in.
