@raphaelmorgan @fullfathomfive You're going to get wildly different answers based on who you ask. I think it could be useful for knowing who's near you if you don't have vision. The only blind-focused company I know of that's doing it in a non-creepy way is Orcam. You explicitly have to show their devices a face and assign a name to that face. Everything is done on device and can't be exported without dismantling the thing. My info is several years out of date, so it's possible that OrCam have changed their ways. Also, I'm not a big fan of OrCam in general. They spend more money on marketting than on their actual products and I've heard nothing but horror stories from their customers. When I attended a presentation in LA, the speaker did a steve jobs schtick and spent half the presentation patting the company on the back. The tech itself is pretty cool though
