Honestly, fingers and movement have been two of the telling signs of AI photos and video for a long time. Just like they've used captchas to crowd-source house numbers for their maps, and vehicle information and street infrastructure for their attempts at self-driving vehicles, they're now crowd-sourcing data for AI images and video.

Plus they'll get geo-information on your location, and video of your immediate area - like the inside of your house. They've had code that processes images and gives feedback on the people in the photo, their likely income and interests, and suggests ads targeted to those people. With geo-location, fingerprinting your phone, and now pictures of the inside of your house, they're really dialing in on their surveillance and ad databases.

Not saying that the opportunity to build facial ID banks isn't a bonus. But don't discount the opportunity to spy inside everyone's homes, and to improve their ability to literally generate their own version of reality - or to produce "evidence" disproving your reality to everyone else.

The phone is where all the datamaning is happening, since its more integrated with your personal data than a computer.
