> They are basically a dash cam for your entire life.

Most people don't want this. Dash cams are for safety and legal liability in a very specific and dangerous domain. These "smart" glasses are for wealth signaling and surreptitiously invading others' privacy. Try walking around with your phone camera recording everywhere you go amd see what kind of response you get from people. Meta's device just obscures the fact that that's what the wearer is doing.
