prompts will give very different results. this is where you do the work.

I disagree. The LLM outputs really do lack anything original or interesting. They just produce banal copy whatever you ask them.

A good editor could probably reduce all LLM outputs on a subject down to the same point.

A controller has to be at least as complex as what it is supposed to control.

Yes but not very different results (unless you're adding new information to your prompt or reducing some ambiguity). Prompt engineering is mostly pseudoscience.
