Yeah, but it doesn't work. It's full of inaccuracies.

Unsupervised Source of Truth(tm), what could possibly go wrong?

I don't understand what supervision you want. Worried about inaccuracies? Double check and use it in conjunction with other sources.

I want some supervision. Why is that hard for you to grasp?

There is supervision, just not community-based.

Just like Wikipedia?

With Wikipedia there is the talk page which will alert you to controversies about topics, as well as checking the citations. While Grokopedia has "citations" when I checked many of them didn't actually have anything to do with what they were supposed to be citing.

Wikipedia has 7 billion potential editors. Grokapedia explicitly says we can't edit it.

So, absolutely the opposite thing.
