AI does not have the skillset or the tools required to match Wikipedia's quality. It can definitely create it's own edit process, but it's a useless one for people like me that don't treat the internet as a ground-truth.
That "rather than cash" bit is bizarre, since no wealthy person holds primarily cash. I checked the pages of several other ultra-wealthy people and none of them have that comment. I'm sure this has nothing to do with Grokipedia's owner recently making an issue of how little cash he holds.
