There isn’t a single human in this world and hasn’t ever been that meets your happy-enough standard. Make of it what you will.
replyIt's not a binary thing. You can get closer or further away from that standard.
replyAnd humans also behave differently in different contexts. A conversation at the pub has more such hallucinations than a formal deposit in court. For the latter, a good lawyer will look at her shoes, when you ask him what colour her laces are.
Why is that at all relevant?
replyHumans are known to hallucinate a lot. Ask 10 different witnesses at a crime scene what they saw and they'll all report different things.
A good, non-hallucinating LLM would only report things for which it has evidence. It would consult the facts every single time.
It's a pain in the butt for humans to fact-check everything but LLMs can quickly look up all kinds of stuff. That's what makes them useful.
