Nobody willingly reads docs. Docs don't exist for the reader, they exist for the writer(s) - because it saves them having to explain the same thing over and over again. Having docs is nice for continuity and for the people who take initiative to seek them out instead of just asking others, but their real value is turning daily (or hourly) 30 minute explanation into a link and a "let me know if you have any questions". The doc pays for itself the second time someone asks you about it.
If they can tell it is written with AI, then the docs are slop. If you're writing something lots of people will use, don't skimp on model or reasoning level, and front load with style guides and examples.
The new key for documentation is that it doesn't need to be was by humans. Good docs are just as valuable whether people read them, or just ask an LLM and the LLM RAGs the information from your docs. The main difference you have to focus on nowadays is ensuring your documentation, even internal documentation, has good "SEO" that it gets looked up.
