Agreed. How well you understand the problem domain determines the quality of your instructions a s feedback to the LLM, which in turn determines the quality of the results. This has been my experience, it works well for things I know well, and poorly for things I'm bad at. I've read a lot of people saying that they tried it on "hard problems" and it failed; I interpret this as the problem being hard not in absolute terms, but relative to the skill level of the user.
