As rachofsunshine suggested, there are quite a few factions and splinter groups within the larger "rationalist" subculture, not just people who happen to be trans and were recruited because of it. My takeaway after spending a few hours down the rabbit hole is that they all seem to be composed of very smart people who have a screw or three loose.

I'm afraid that at some point, some of these people are likely to talk themselves into doing something seriously fucked up. If I worked on AI at OpenAI or Google or Meta, I think I'd prefer to work from home... and if I occupied a visible position on the org chart, I'd hire a damned good private security company to keep an eye on my family.
