A couple of years ago the OCaml and Julia languages already had to deal with a content farm that created wikis for them, filled them with LLM-generated, blatantly wrong or stupidly low quality content, and SEOed its way above actual learning materials. Cue in the newbies to these languages being incredibly confused.
This at least tries to generate the text out of the actual project, but I'm pessimistic and think it'll cause similar confusion.
Annoyingly, anyone can just.. request a deepwiki for any GitHub repo. That one exists doesn't mean that it's endorsed or reviewed by the project.
They just kind of barged in, welcome or not. Just another SEO slop-spammer.
