Since you seem to have not noticed my comment above, here's another example of a project that implements many of these techniques. Me and many others have used this to transcribe hour long videos into a well organized "docs site" that makes the content easy to read.
Example: https://matadoc.vercel.app/
This was completely auto-generated in a few minutes. The author of the library reviewed it and said that it's nearly 100% correct and people in the company where it was built rely on these docs.
Tell me how long it would take you to write these docs. I'm really confused where your dismissive mentality is coming from in the face of what I think is overwhelming evidence to the contrary. I'm happy to provide example after example after example. I'm sorry, but you are utterly, completely wrong in your conclusions.
