It's californication into the "rationalist" community as it currently stands is no surprise. Every person I've met deep in this community either seemed to me a narcissist (if male) or, politely and mildly, coquettish (if female). With several relationships I've observed a clear union of the two. I hadn't yet put this so clearly together with the "AI Saftey" crowd, despite being directly adjacent to it all for quite awhile and seeing the cross-proliferation.
My own analysis had concerned their philosophical naivety, general lack of actual computer science knowledge and generic shallowness of understanding of any domain outside their own research and a kind of "science-fiction" version of philosophy and rationalism. I hadn't connected this yet to their strange personalities, but the apoclypticism fits and neatly bridges these together.
So what became of the New Atheist project to create a "secular religion" -- an apocalyptic sex cult furnished by a blend of sci-fi, pop-philosophy, and cute parables from polymath medical professionals. All in all then, it seems they succeeded.
