For the author it matters. To which degree do they want to be associated with the resulting text.

And I differentiate between "Matt Godbolt" who is an expert in some areas and in my experience careful about avoiding wrong information and an LLM which may produce additional depth, but may also make up things.

And well, "discern the quality of the contents" - I often read texts to learn new things. On new things I don't have enough knowledge to qualify the statements, but I may have experience with regards to the author or publisher.
