It is illegal if you send a delete request.

The question is here, if ‘delete account’ is the same as asking Meta to delete all data in the regard of GDPR. My guess is, its not.

There’s also no way they will retrain their AI without your data, just because you told them to.

Its a little more complicated than that I think. LLMs and AI is not remotely the same with very different use cases.

I believe in AI for sure in some fields, but I understand the skeptics around LLMs.

But the difference AI is already doing in the medical industry and hospitals is no joke. X-ray scannings and early detection of severe illness is the one being used specifically today, and will save thounsands of lives and millions of dollars / euros.

My point is, its not that black and white.
