I was in engineering school back in ~2012 when Google Glass came out. One of my classmates got hold of a pair when they were still quite uncommon and wore them to an extracurricular club meeting. Within minutes someone made a comment about him wearing the "creeper" glasses and asked if he was filming. He never wore them to the club again. I just don't see a world where that doesn't happen with Meta glasses.
It's strange to me that that's the line society seems to have drawn in the sand. Body cam, no problem. Doorbell cam, practically universal. Body cam worn on the face? No way. I wonder why.
Cops also announce their presence in uniforms and are operating as government agents. People already moderate their behavior around cops so being recorded isn’t as big a deal.
