I understand it has no sense of knowledge-of-knowledge, so (apparently) no ability to determine how confident it ought to be about what it's saying — it never qualifies with "I'm not entirely sure about this, but..."
I think this is something that needs to be worked in ASAP. It's a fundamental aspect of how people actually interact. Establishing oneself as factually reliable is fundamental for communication and social cohesion, so we're constantly hedging what we say in various ways to signify our confidence in its truthfulness. The absence of those qualifiers in otherwise human-seeming and authoritative-sounding communication is a recipe for trouble.
It is scary in the sense that people love following confident sounding authoritarians, so maybe AI will be our next world leader.
I don't mind it giving me a wrong answer. What's really bad is confidently giving the wrong answer. If a human replied, they'd say something like "I'm not sure, but if I remember correctly..", or "I would guess that..."
I think the problem is they've trained ChatGPT to respond condidently as long as it has a rough idea about what the answer could be. The AI doesn't get "rewarded" for saying "I don't know".
I'm sure the data about the confidence is there somewhere in the neural net, so they probably just need to somehow train it to present that data in its response.
