The way LLMs work at the moment is equivalent to going to a doctor with a set of symptoms, and the doctor telling you "ah yes, of course, it's illness X and you need to take medicine Y to cure it" and then you check and neither X nor Y exists. That's not "accuracy" that's just straight up fraud?
I wouldn't have any problem with Google's AI saying "I don't know" or "I don't have enough sources to provide a good answer, but my best approximation is this". But I literally battle misinformation produced by Google's AI search every single day, because it's telling people actual made up facts that don't exist.
