If you stop and think, LLMs seem to operate very much like humans.

Go to any human and ask it a question, and it will answer either from direct specific experience, or from estimation based on its experience.

We highly value humans who have a lot of direct experience and also can extrapolate that experience or apply it to new scenarios and generate believable answers.

In other words, unless a human has exact knowledge, they are "hallucinating". It's very normal.

The point is, whether LLM or human "expert", if the question is of great significance, get a second and maybe third opinion.

At the end of the day, this is all an experiment. And nothing matters, because it will all turn to dust.
