In case you've never seen it before, you can watch how a burger's made (in case of LLMs anyway) and eventually replicate it. You can also inspect the recipe after the fact to learn.

Nobody says it does. However, if I am solving big business problems and making enough to justify a private cook, why wouldn't I do that to optimize and focus on my area of expertise?

I don't want to be a code monkey. I want to talk to business people and come up with solutions. I don't care if LLM writes most of it or a junior dev...well I do LLM is better.
