> I don't care much about my name being public, but I don't know what else it might have memorized (political affiliations? Sexual preferences? Posts from 13-year old me?). In the age of GDPR this feels like an enormous regression in privacy. It's an interesting question! One of the reasons for GDPR was 'the right to be forgotten'. Deleting of old data, so that things you did 10 years ago don't come to haunt you later. But how would this apply to machine-learning models? They get trained on data, but even when that data is deleted afterwards that information is still encoded in the machine-learning model. If it's possible to retrieve that data by asking certain questions, then imo that model should be treated as a fancy way of data-storage, and thus deleted also.
