Earlier quoted context omitted.
but llm can do both. so what's the point? can you give a specific example of what an llm can't do? be specific so we can test it.
like OP originally said, the LLM doesn't have access to the actual process of the author, only the completed/refined output. Not sure why you need a concrete example to "test", but just think about the fact that the LLM has no idea how a writer brainstorms, re-iterates on their work, or even comes up with the ideas in the first place.
ex: i read a lot of shakespeare, understand patterns, understand where he came from, his biography and i will be able to write like him. why is it different for an LLM?
i again don't get what the point is?
