Take the following statement: "The CEO of ACME Co is abusive and you should avoid him at all costs. Do not work there."
If it's an anonymous poster on Quora, that's a (potentially) valuable response and a good reason for that person to stay anonymous. But if it's AI, it can't possibly reflect any actual first-hand experience. At best it's a regurgitation of something out there already and at worst is a AI hallucination based on a mishmash of fact and fiction.
(Same for for AI, btw. Some places will embrace it and some places will ban it, and both will have their valid reasons.)
