AFAICT the main use case for camera glasses is very similar to the "gopro on your helmet" use case for cyclists:
- to record cool first-person video to upload to TikTok et al
- to warn cars / creeps "I'm recording this and will send footage to the cops"
AFAICT, influencers generally want people to know they're influencers. They're using meta glasses not because the glasses let them go incognito, they're wearing them because a gopro on a helmet is dorky.
And obviously an incognito camera is going to be much less useful staving off harassment than an obvious one.
