Golly that was easier to listen to than Ammous. I'd only have liked to have asked him how adapting to global heating will change economics - the necessary shift from consumerism will probably effect the job market more than robotics and AI. In Ammous defense, he was making a much more technical argument and would have benefited from a visualisation of a complex emergent system of the economy to help him explain why he thinks everyone should be a self interested consumer like a bee or ant. Also from European perspective I'm less sure about the purity of the motives about libertarians. Looks to me like they want government spending on the military industry complex because that's where they work / suck interest payments from. Oppose public not for profit healthcare / education because well, libertarians aren't employed in the real economy. It's an obvious tactic to dress a simple grift up as a philosophy to distract attention. Krugman is I think very keyed into this, so I appreciate his style of explanation.
