IMO I think it is a combination of being a really great programmer already and then either not all that intellectually curious or so well read and so intellectually curious that LLMs are a step down from being a voracious reader of books and papers.

For me, LLMs are also the most useful thing ever but I was a C student in all my classes. My programming is a joke. I have always been intellectually curious but I am quite lazy. I have always had tons of ideas to explore though and LLMS let me explore these ideas that I either wouldn't be able to otherwise or would be too lazy to bother.

I don't totally follow what you're saying.

Are you saying that LLMs are most useful if you're not intellectually curious, and therefore most interested in immediate answers, but also that they're very useful if you're a really great programmer for an unstated reason?
