This argument is specious and boring: everything an LLM outputs is "hallucinated" - just like with us. I'm not about to throw you out or even think less of you for making this mistake, though; it's just a mistake.
QAnon folks, for example, are biological models that are trained on propaganda and misinformation.
Trauma victims are models trained on maladaptive environments that therapists take YEARS to fine-tune.
Physicians are models trained on a corpus of some of the best training sets we have available, and they still manage to hallucinate misdiagnoses at a staggering rate.
I don't know why everyone here seems to think human brains are some collection of Magical Jesus Boxes that don't REGULARLY and CATASTROPHICALLY hallucinate outputs.
We do. All the time. Give it a rest.
