YouTube to gauge US users’ ages with AI after UK and Australia add age checks

Tech company says it will use machine learning to estimate ages in order to show users in US age-appropriate content

YouTube announced on Tuesday that it will begin to use artificial intelligence to estimate the ages of users in the US, in order to show them age-appropriate content.

The rollout of the new feature comes one day after Australia's government announced it would ban children under 16 from using YouTube and less than a week after the UK implemented sweeping age checks on content on social networks.
