In an effort to protect young users, ChatGPT will now predict how old you are

Honestly? This is security theater. They're adding a classifier to guess your age, which means it'll be wrong 30% of the time and users will route around it in five seconds (VPN, Discord accounts, whatever).

Here's the thing: you can't age-gate a text interface. COPPA learned this in 2000. OpenAI's doing this because regulators demanded something, not because it actually works. It'll appease EU/UK auditors for a quarterly report, then everyone moves on.
