The effective altruism/rationalism/AI xrisk people have always had a shockingly poor grasp on subjects outside computer science, despite their attempts to speak on them. I don't blame the actual biologists and chemists working at the frontier labs for wanting to skim a few bucks off all the money flying around, though! I know a couple who've had not-so-kind words to say about their employers' intelligence.

I suspect there's at least some "telling the bosses what they want to hear" going on. A massive financial incentive exists to exaggerate and fearmonger even internally to the company, because it makes you and your job seem more important.

They also have a shockingly poor grasp of computer science.
