I agree to an extent. He does remind me of people I've known in the rationalist movement. It's worth pointing out that him blurting out the wrong thing at the wrong time isn't just an annoying character trait, it's probably symptomatic; I'd speculate he doesn't really consider other people as fellow actors in his decision making. If there was someone who did not make efforts to bond with people around him, would you be willing to trust him with power over their happiness?

That's a non hypothetical question, I'd love to hear a rebuttal.
