> This is the dangerous thing that Wikipedia has already done in part, but instead of being on one particular site that any informed person knows should not be trusted on certain issues, it will be the background narrative for the entire internet and all people who rely on it for their thoughtless decisions.

The neat thing about Wikipedia is that you can, actually, edit it. And pages do change over time to reflect new sources and new consensus, after discussion and, sometimes, debate. Wikipedia also strongly grounds its content in citations and secondary sources, while AI slop generally does not.
