Competency is required to intentionally hinder human flourishing at that scale. It is very much an issue of competency and foresight. I agree that the centralization presents issues since the cost of mistakes is much higher than in a decentralized system. There’s also the problem of iterations which is harder with more centralized systems. He’s in favor because he thinks the system is out to get him; I’m in favor because I think the system is fundamentally incompetent. Make sense?
