Given this feature seems to be premised off guessing a user’s age based on their inputs, and a common use case for Claude it uploading personal legal and tax documents to have Claude explain them to you, I am guessing Anthropic is not hurting for data about their customers.

Seems more likely this is designed to stave off similar laws /regulations to what the social media platforms are now being hit with, and moving liability from Anthropic to parents. If dad lets kid use his Claude account for a school project, and Claude ends up telling the kid to hurt himself, it’s now dad’s fault.
