Don’t get me wrong, I’m all for privacy. But between setting up the birthdate when creating my children’s local account on their computers, and having to send a copy of their ID to every platform under the sun, I’d easily chose the former.
I’d even agree to a simple protocol (HTTP X-Over-18 / X-Over-21 headers?) to that.


The goal isnt to herd every single cat. Just get the bulk of them. That’s how existing age regulation works. Alcohol age limit doesn’t stop underage drinking, but it does substantially reduce it. With that in mind, there are privacy respecting solutions that will do what needs to be done
I doubt you would even get “the bulk of them”. Again, people are saying “it’s just a yes/no tickbox bro”. For now. You cannot be naive enough to think it won’t change. And the absurdity of it too. Forcing something someone may program for fun to have a specific feature.
I do expect it to change. I expect it to be standardized with zero knowledge proofs. If I am avle to communicate with you on a random internet forum from anywhere in the world using standardized protocols, we can get private and secure “I am 18+” verification. It may initially start with proving it in some form or another, but if done correctly you would essentialy have a private key that certifies you are over X age. The company would know nothing about you, other than you are not a child. I have extremely simplified it, but it is possible.
Many OS here aren’t made by companies. They can all easily just be forked and edited to immediately wave people through any hypothetical age checks, moreover any website could just ignore it and wave everyone through.
