Critics have raised concerns about privacy as well as access to the platform for users falsely flagged as underage.

In a move YouTube says is aimed at providing better protections for younger users, the video giant on Wednesday began rolling out an “age-estimation model” in the U.S. that uses AI to determine if someone is under 18 — regardless of the birthday they’ve entered into their account.

YouTube's AI age verification could significantly expand protections for teens, aligning the platform with mounting regulatory pressure. But the flip side is a new privacy burden on adults who are misclassified and asked to hand over sensitive data to prove their age.
