I mean, of course he loves unfettered technology and capitalism. He's a fucking billionaire. He hit the demographic lottery.
EDIT: I just noticed his list of "techno-optimist" patrons. On the list? John Galt. LMAO. The whole list is pretty much an orgy of libertarians.
I see him more as a dupe than a Cassandra. I heard him on a podcast a couple months ago talking about how he's been having conversations with Bay Area AI researchers who are "really scared" about what they're creating. He also spent quite a bit of time talking up Geoffrey Hinton's AI doomer tour. So while I don't think Ezra's one of the Yuddite rationalists, he's clearly been influenced by them. Given his historical ties to effective altruism, this isn't surprising to me.
