With some controversial topics like Nuclear Power on the German wikipedia or the Gaza conflict on the English one, wikipedia has become less than useless. Once an activist editor sith too much time gets hold of a page, it is game over for neutrality of wokipedia. Grokipedia might introduce some much needed competition.

I think it depends on the subject. Sure, I have heard a historian call it "Wickedpedia" because it gets all the facts wrong. But have a look at the "hash function" page. That is pretty in-depth.
However, this all misses the point that the article is making: It's a store of knowledge added to and edited by humans. At least they're not AI, the article says. I don't know if this is true, but if so, I find it compelling.
