So seeing the reaction on lesswrong to Eliezer's book has been interesting. It turns out, even among people that already mostly agree with him, a lot of them were hoping he would make their case better than he has (either because they aren't as convinced as him, or they are, but were hoping for something more palatable to the general public).
This review (lesswrong discussion here), calls out a really obvious issue: Eliezer's AI doom story was formed before Deep Learning took off, and in fact was mostly focusing on more GOFAI than neural networks, yet somehow, the details of the story haven't changed at all. The reviewer is a rationalist that still believes in AI doom, so I wouldn't give her too much credit, but she does note this is a major discrepancy from someone that espouses a philosophy that (nominally) features a lot of updating your beliefs in response to evidence. The reviewer also notes that "it should be illegal to own more than eight of the most powerful GPUs available in 2024 without international monitoring" is kind of unworkable.
This reviewer liked the book more than they expected to, because Eliezer and Nate Soares gets some details of the AI doom lore closer to the reviewer's current favored headcanon. The reviewer does complain that maybe weird and condescending parables aren't the best outreach strategy!
This reviewer has written their own AI doom explainer which they think is better! From their limited description, I kind of agree, because it sounds like the focus on current real world scenarios and harms (and extrapolate them to doom). But again, I wouldn't give them too much credit, it sounds like they don't understand why existential doom is actually promoted (as a distraction and source of crit-hype). They also note the 8 GPUs thing is batshit.
Overall, it sounds like lesswrongers view the book as an improvement to the sprawling mess of arguments in the sequences (and scattered across other places like Arbital), but still not as well structured as they could be or stylistically quite right for a normy audience (i.e. the condescending parables and diversions into unrelated science-y topics). And some are worried that Nate and Eliezer's focus on an unworkable strategy (shut it all down, 8 GPU max!) with no intermediate steps or goals or options might not be the best.
