I oppose this for 3 reasons, presented in no particular order:
Pseudo-medieval-Europe setting. Yeah, yeah, I know it isn't an ironclad rationale given the non-European things already in-game, but still.
I hate potatoes. Yes, it runs in the family, no, we don't know why, and yes, it sucks - do you have any idea how many foods people just shove potatoes into because everyone else finds them innocuous?
I really, truly, deeply don't want ChatGPT deciding what goes in Vintage Story. I lied, this one's last because it's the most important (and it also explains the "sorta right but also doesn't engage with the potato's actual history in any meaningful way" vibe the whole post gives).
