I mean, in theory we do. An AR display or earpiece with lots of sensors would be cool.

But these companies have all poisoned the well. No one trusts them nor users on their platforms anymore.

EDIT: In case we forgot, half the problem with the Meta glasses IS Instagram. They created a space where macho jerks can get super rich live-streaming being a jerk, so of course thats what they will use the glasses for.

Otherwise it could be a neat idea, but we are not in that universe.
