> Yes of course relationship questions don’t have a “correct” answer. But physics questions do. Code vulnerability questions do. Math questions do. I mean seriously?

But as per Gödel's incompleteness theorem and the Halting Problem, math questions (and consequently physics and CS questions) don't always have an answer.

Providing examples of questions without correct answers does not prove that no questions have correct answers. Or that it’s hallucinations aren’t problematic when they provide explicitly incorrect answers. The author is just avoiding addressing the hallucination problem at all by saying “well sometimes there is no correct answer”

There is a truth of the matter regarding whether a program will eventually halt or not, even when there is no computable proof for either case. Similar for the incompleteness theorems. The correct response in such cases is “I don’t know”.
