It looks like a forum post where somebody showed their inaccurate ChatGPT results got boosted to the top of Google's ranking somehow. I think this is more of an issue with YCombinator's SEO abuse than anything. There's a reply from just 1 day ago on that forum post that says:
I just searched "country in africa that starts with k" and it used your comment as a snippet answer
EDIT: I also sent feedback on that result. I suggest others do the same if you see it. Only way these things get fixed is if they're reported to the people who can fix them.
