Not to you, although I would bet it has done so to someone. The main issue is though, if you asked an LLM to write arguments for a flat earth, it would do so. Convincingly and insistent, without even questioning or critically analyzing why. Ask it to compare and balance arguments both ways. And it will do so as if both positions were equally real and valid.

It has no notion of reality and no convictions of its own.

It will also hallucinate fake papers and quote people that don't exists to make its argument.

PS: most poignantly, the point of the paper is that it says, over and over, "this information is false, this disease doesnt exist. All of this is made up". Unlike the other problematic papers quoted on this comment thread that were published with conviction by the authors, and later were retracted. Yet the LLM is unable to parse that tidbit of information. It is not as smart as the most stupid. It simply is not intelligent, not even as intelligent as the most stupid humans. You can tell it, the following sentence is false, and it is not smart enough to pick up on that meaning.
