It's been getting bad for awhile, top search results are normally pay walled... less content from individual blogs. Facebook is a complete walled garden it's content isn't even indexed. Facebook, reddit, discord, etc have almost completely killed special interest forums.

Now there is a small chance AI generated content could get more content available not behind paywalls, with more small and micro publishers. But getting rid of the factually inaccuracies and hallucinations would be a huge task, that google doesn't seem to be capable of, at least their recent blunders suggest.
