You've likely seen the new age verification requirements for all electronic operating systems, Linux included. So, to comply they just need to check your age and then tell websites that you are an adult or a kid.

Next, they will say, oh.. that's too easy to bypass, we need to have your realID to verify it's you, but don't worry, we wont store that.

Then, oh.. AI can make very realistic images so we need your DNA and need to always check what's happening on your computer against your real ID.
