Yudkowsky is a human LLM: his output is correctly semantically formed to appear, to a non-specialist, to fall into the subject domain, as a non-specialist would think the subject domain should appear, and so the non-specialist accepts it, but upon closer examination it's all word salad by something that clearly lacks understanding of both technological and philosophical concepts.
That so many people in the AI safety "community" consider him a domain expert has more to say with how pseudo-scientific that field is than his actual credentials as a serious thinker.
