- they have the opportunity to save the video feed at any time - they are probably storing some kind of metadata of the feed, maybe some kind of analysis output - someone could hypothetically watch it
I thought it was dangerous because I thought they could do what they're doing, but I didn't think that right now they actually were and so overtly
The data required is small. Each embedding might be 1/2 kB per face.
> power budget
To process a video for biometric feature extraction, it might take 0.5% to 2% of the total power used to record a video. Video uses a lot of power (compression, screen, etc)
Assuming you've got a modern device (e.g. with Apple Neutral Engine). Disclosure: Googled info (Gemini).
It wasn't Meta's morals that gave me any signals to that effect. It was the potential legal minefield on top of the engineering challenges [1] that made it so I didn't even consider this as a possibility. In fact I'm still confused. I don't understand how they would be pulling this off despite those challenges, and I would love to.
