>In that case we are walking video cameras violating people's privacy everywhere we go

This is actually not true in the US. So people should be careful and understand their rights.

In the US, the government affords us no expectation of privacy when we are in public. As soon as you step out of the hotel room you and your mistress went to at lunch, it's completely legal for a private investigator to snap photos or record video of you.

Basically, when you're out in public in the US, you have no right to privacy. So when people have amazon rings, or google glasses, or brain interfaces that record everything while they're in public, all that information is fair game for the authorities in any court action.

Business idea: Privacy zones. No photography, no video-recording, no audio-recording. In fact, maybe some venues would even ban phones (like a SCIF!).

And, facial ID scanning at the door to ban repeat offenders.

For sex and swinger clubs this would be ideal. Keeps the privacy of the inside intact.
