Tyler Cowen — Hayek, Keynes, & Smith on AI, animal spirits, anarchy, & growth

Tyler Cowen, Hayek, Keynes, Smith

Tyler Cowen critically evaluates John Maynard Keynes' concepts of "animal spirits" and long-term investment skepticism while analyzing the social optimality of overconfidence and market liquidity. He further contrasts the historical breadth of economists like John Stuart Mill with modern specialization, arguing that markets function as decentralized discovery processes rather than computational equilibrium solutions. Looking forward, Cowen predicts that AI will drive a return to 19th-century growth rates through human-AI productivity bifurcation while warning that technological intelligence amplifies existential risks that require robust, albeit precarious, decentralization.
