In my case, where I see it most often is when the LLM has to rework something multiple times, and the feedback loop is vague (especially when all I have to give it is "no error messages, but it's still broken"). It seems like after the third or fourth try it just kinda goes off the rails. I find that the one-shot quality tends to be a little better, if the slot machine happened to work correctly that time.

So with LLM outputting average code, and people using LLM more and more, I guess the average code will become worse over time ?
