I do not think Faulkner would write very good C++ library documentation.

I would read the hell out of Joyce’s Perl 5 documentation, but only after six or seven beers.

There's an art to it. Most human attempts, and every LLM attempt I've ever seen, are awful, sometimes bordering on unreadable, but, as you say, there are a relatively small number of authors who do it well. That doesn't mean that most people should do it.

I'm a French speaker and florid and elaborate writing is something I've grown up with. It can be difficult if you don't know the word or are not used to the style, but it's not boring. AI writing is just repetitive.
