Wikipedia is a great educational resource and one I've donated to for over a decade. That said, I like the idea of Grokipedia in the sense that it's another potential source I can look at for more information and get multiple perspectives. If there's anything factual in Grokipedia that Wikipedia is missing, Wikipedia can be updated to include it
I hope we can keep growing freely available sources of information. Even if some of that information is incorrect or flat out manipulative. This isn't anything new. It's what the web has always been
