The "AI safety" movement is largely an answer to only one side: the apocalyptic one. Doomers like Yudkowsky and his ilk are popular over there. Note how his most recent book reads like scifi, including with its implausible "solutions"? These people are living in a fantasy land. This isn't to say p(doom) = 0, but we've lived with it being non-zero since the introduction of nuclear weapons. Very little has changed there, I'd say.
For the socio-realism side, well, this model aligns well with exactly the kinds of real-world misery often posted on this site, as intellectual workers' livelihoods and telos are negated by automation. Sellers of "AI safety" don't care about them. There's no calls from that community to carve out space for us to retain a life of meaning within society when our ability to contribute is nullified. The fantasy of AI safety doesn't have room for that: they're too busy warding off imaginary demons; hence the cult-like behavior.
