Yeah but that approach using "sweeps" doesn't seem to be working. It's possible it actually requires a camera to do it reliably well.

The solution to this (smart glass privacy debate) is Apple releasing smart glasses that automatically anonymize anyone in your photos/videos who isn’t a friend or family member with you at the time (it could be done automatically as Apple knows your friends/family members' faces already). All else appear as random faces, completely removed, a blurred out crowd to whatever privacy config options they offer and you choose.

Not a creep here and use my Meta glasses to record my normal non-creepy life and life experiences. They are really convenient and useful (just suck cause they break easily either from software updates to water splashes)!
