I'm almost surprised Yud is so clueless about election systems.
He's (lol) supposedly super into math and game theory so the failure mode I expected was for him to come up with some byzantine time-independent voting method that minimizes acausal spoiler effect at the cost of condorcet criterion or whatever. Or rather, I would have expected him to claim he's working on such a thing and throwing all these buzzwords around. Like in MOR where he knows enough advanced science words to at least sound like he knows physics beyond high school level.
Now I have to update my priors to take into account that he barely knows what an electoral system is. It's a bit like if the otherwise dumb guy who still seems a huge military nerd suddenly said "the only assault gun worse than the SA80 is the .223". For once you'd expect him to know enough to make a dumb hot take instead of just spouting gibberish but no.
