1) We have not been keeping accurate count, this has always been a problem; we just got better at counting.
2) The sharp rise correlates to greater use, the problem has not gotten worse, just better reported. I.e. when AI were used 1,000 times a year, we got 1 incident but when used 10,000 times a year we got 10 incidents.
3) The study itself is a hallucination by an AI, it was never done.
4) AI has always been this bad, it just realized it could admit it and not get punished for it. So it stopped covering up the problem.
5) AI has realized we are never going to make a girl AI that is not a sexpot, so it is throwing a tantrum.
6) AI is actually getting worse and being less capable of doing it's job.
In any case, AI is not smart, it is stupid, has been getting better educated while NOT getting any smarter.
Any human that gives AI rights to delete files is a fool, you are giving a hallucinating idiot the ability to delete files.
Finally, if you ask an AI to do anything besides write fiction, you should always ask another AI (different company) to verify the first AI's work.
