Because published books, depending on genre, have earned a presumption of being based on reality. And it's easy to reproduce a book lookup, and see if they link to sources. I might have experience with that book and know of its connection with reality.

ChatGPT and similar have not earned a presumption of reality for me, and the same question may get many different answers, and afaik, even if you ask it for sources, they're not necessarily real either.

IMHO, it's rude to use ChatGPT and share it with me as if it's informative; it disrespects my search for truth. It's better that you mention it, so I can disregard the whole thing.
