The Forgetting Dilemma: Why AIs Can Hardly Delete Personal Data
Validated facts
Machine unlearning is mathematically unsolved. Once a phone number or address is baked into a model's billions of parameters, you cannot delete it at the push of a button like in a database.
In plain language
Spilled milk in the cake batter: You cannot simply pull the milk back out of the baked cake without throwing the whole cake away.
Security relevance & practical tip
Conflicts with the GDPR right to be forgotten (Art. 17). Whoever trains on sensitive data risks having to delete the entire model.
