If "hallucination" refers to mistaking the product of internal processes for external perception, then generative AI can only hallucinate, as all of its output comes from inference against internal, hard-coded statistical models with zero reconciliation against external reality.
Humans sometimes hallucinate, but still have direct sensory input against which to evaluate inferential conclusions against empirical observation in real time. So we can refine ideas, whatever their origin, against external criteria of correctness -- this is something LLMs totally lack.
