> The social media company requires users to take a selfie video on their phone and uses AI to estimate the person's age.

What I did not see in this article was anything about how AI can tell a 13 year old from a 12.9 year old with confidence. This seems unlikely to me.

I agree with the article's implication that websites will now want a scan of everyone's faces forever. Their insistence that they won't store the face scans is like one those cute lies that kids tell, and adults aren't fooled by. Either you're outright lying, or you're using the loophole of not storing the image, but rather storing a set of numbers, drived from the image, which act as a unique fingerprint. Or, you're sending it to a third party for storage. Or something like that. But you're definitely keeping track of everyone's faces, don't try to pull a fast one on me young lady, I've been around the block before.
