Along the way they discuss why financial markets are unusually good at error-correction, why "wanna bet?" functions as a tax on bullshit, and what it means that every senior economist Aaron told about the tractor problem simply laughed and topped it with a worse story. – Full transcript available here: https://www.complexsystemspodcast.com/aaron-brown/ – Presenting Sponsors: Mercury & Granola Complex Systems is presented by Mercury—radically better banking for founders.
