@Catvalente "Hallucinate" might not the best choice of words, but LLMs don't error out like traditional programs and apps. LLMs make mistakes, they misremember, they confabulate, they bullshit; which is something we're NOT used to seeing from computers; it may not (necessarily) infer consciousness, but it's something uncomfortably ... familiar.
Computer programs don't make mistakes, they may encounter scenarios not accounted for by their programing. Assuming there's no hardware issue or data corruption, a calculator app will NEVER make an arithmetic error. You can put in a calculation in a million times, and it will always give you the same answer.
