I have not found any of several models that I have tried to be very discerning with its searches. It will often take just the most recent web posting and treat that data as gospel truth, no matter how wrong or irrelevant it might be. AI is something like a fool. It asserts righteously that it knows the correct answer when it is not even close. It would do better to shut up and leave some doubt as to its worth rather to openly display how incorrect it often is. It requires very careful queries and even more careful review and editing. Not ready for prime time. IMHO
An excellent observation. In addition to companies marketing their "not ready for prime time" products, your comparison of AI to a fool speaks, when one thinks of the traditional court jester. Meant to entertain.
--- "...the most recent web posting and treat that data as gospel truth...." This is what these Large Language Models do. Find something and paraphrase it, without having the ability to see through contradistinctions and human errors. Research engines for specific things is something they can do, but that is not intelligence. It is e-paperwork, filing and retrieving.
Best wishes.
