> a time-to-unlearn kind of an acceptable agreement Why put the burden to end users? I think the technology should allow for unlearning and even "never learn about me in any future models and derivative models".
No technology can guarantee 100% unlearning, and the only 100% guarantee is when the data is deleted before the model is retrained. Legally, even 99.99% accuracy may not be acceptable, but, only 100%.
The law cuts off at some point, and declares it 100%.
