I couldn't even make it through this one, he just kept repeating himself with the most absurd parody strawman he could manage.

This isn't the only obnoxiously heavy handed "parable" he's written recently: https://www.lesswrong.com/posts/dHLdf8SB8oW5L27gg/on-fleshling-safety-a-debate-by-klurl-and-trapaucius

Even the lesswronger's are kind of questioning the point:

I enjoyed this, but don't think there are many people left who can be convinced by Ayn-Rand length explanatory dialogues in a science-fiction guise who aren't already on board with the argument.

A dialogue that references Stanislaw Lem's Cyberiad, no less. But honestly Lem was a lot more terse and concise in making his points. I agree this is probably not very relevant to any discourse at this point (especially here on LW, where everyone would be familiar with the arguments anyway).

Reading this felt like watching someone kick a dead horse for 30 straight minutes, except at the 21st minute the guy forgets for a second that he needs to kick the horse, turns to the camera and makes a couple really good jokes. (The bit where they try and fail to change the topic reminded me of the "who reads this stuff" bit in HPMOR, one of the finest bits you ever wrote in my opinion.) Then the guy remembers himself, resumes kicking the horse and it continues in that manner until the end.

Who does he think he's convincing? Numerous skeptical lesswrong posts have described why general intelligence is not like chess-playing and world-conquering/optimizing is not like a chess game. Even among his core audience this parable isn't convincing. But instead he's stuck on repeating poor analogies (and getting details wrong about the thing he is using for analogies, he messed up some details about chess playing!).
