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

YouTube began rolling out an 'age-estimation model' in the U.S. that uses AI to restrict access to users determined to be under 18 years old.

If the technology incorrectly estimates a user to be under 18, they can verify with a credit card or a government ID. YouTube said it will only allow users who have been verified over 18 to view age-restricted content that may be inappropriate for younger users.
