I don't think everyone shares those doubts. The first time you catch an LLM in a lie is sobering, but there are lots of areas, and thus lots of users, for whom it doesn't hallucinate for, because they're asking softball questions and it doesn't end up hallucinating, or hallucinations just really aren't aren't that big a deal. (eg an LLM horoscope generator or using it write sci fi.)
so while we're on HN going back and forth about how outright lies by the system indight the whole thing for everybody, we should be careful to note that it's not for everybody, or rather, it's a known limitation so don't trust it to cite real cases for you as a lawyer, but using it to help you figure out what mens rea means in a practical sense by asking it questions about the concept, totally.
Honestly, hallucinations happen so rarely for me because of the kinds of things I ask it, that it doesn't happen enough for me to not believe it's answers in low-stakes situations, or situations on the level of horoscope generation, and I'm sure I'm not alone in treating ChatGPT that way, despite evidence to the contrary.
