The most malicious use of AI would be using it as a cover for the elites to perpetrate stuff that is way out of the current Overton window, and blame AI for that.
If I write a virus I'll get the various cybercrime units on me. The LLM companies don't get a pass if their software does something malicious.

(have you tried turning it off when you realised it was doing something bad?)
