I think it’s just very alien in that things which tend to be correlated in humans may not be so correlated in LLMs. So two things that we expect people to be similarly good at end up being very different in an AI.

It does also seem to me that there is a lot of variance in skills for prompting/using AI in general (I say this as someone who is not particularly good as far as I’m aware – I’m not trying to keep tips secret from you). And there is also a lot of variance in the ability for an AI to solve problem of equal difficulty for a human.
