If you go far enough in a field, you start to recognize areas where your personal opinion differs from the “best practices” usually recommended.

I think by design an LLM can’t do that. It’s built to reflect the distribution of the knowledge it has been trained on.

absolubtely. Any random junior consultant can tell you what the book tells you you should do. If you want to actually do anything worth doing, you need to step beyond that in a few, limited areas, and follow convention everywhere else. Which areas? pay a senior engineer and they'll find them.

surely the LLM can do that. It is RL'd against some reward, if the known strategies are clearly suboptimal with easy improvement, it'll find it most likely
