Here's the problem imo: most of Wikipedia's content is currently unmaintained (as far as I can tell).
If there's any political or nationalistic controversy to the content, there's 50 wikilawyers obsessively monitoring it. But if the article is 'boring', anyone can go in there and write whatever they want and (unless a bot thinks it's vandalism), nobody will care.
This is natural - it's fun to write an article and collaborate on edits. Then you move on, because no normal person wants to be the content janitor. And what happens to the article 5 years later? How about 10 or 20 years? I think if Wikipedia doesn't get a handle on this, on the structural level, the site is going to be mostly random agrammatical garbage sooner-or-later.
Wikipedia is already at the point where it seems like every article has content warning banner on top of it. Most of them have been there for years, and nobody cares.
