It's going to be interesting to see how one can use cryptography to do this privately. I wonder if the cost and complexity of such a thing would result in big companies simply requiring some kind of "take a picture of your ID" style verification.

Estonia's ID card https://www.id.ee/en/ could certainly be a model; still not sure how to do age verification. My best guess would be some sort of cryptographic signing that refuses to sign if you are below a certain age.
