I went on Grokipedia once, months after launch out of curiosity. I found an error in the first article I looked at (the city that I live in). It was in the first sentence of the first paragraph of the History section.

It conflated erroneously King William the Lion of Alba and King William the Conqueror of England. They weren’t even alive in the same century.

I can absolutely follow the logic of how Grok would make the error. Both Kings, both William, both the first of their name in their respective kingdoms, both notable and significant in their own right, but definitely not the same person.

The 50+ y/o gay bus driver that is a regular at one of my local pubs has/had an account strictly for rage baiting those who he calls “MAGATs”. I enjoy the enthusiasm but we live in Scotland so I’m not sure I’ll be joining him.
