I'd imagine some recognition technology could take into account body proportions, posture, (commonly worn) apparel, etc. to make facial recognition less needed.
It's the obvious malicious intent that we see time and time again with Facebook, the companies they own, and like-minded companies like Google and Amazon. People are fed up with the BS. It's atrocious that no tech people speak out or get the airtime to inform people what's going on without their knowledge (and most of the time, consent). Facebook is a scourge to humanity.
Funny how they're adament that Facebook doesn't utilize microphone (while they still don't really know themselves). Why is it laughable that Facebook is using both the FB Pixel, microphone, and other technologies to spy?
