Planning Problem

Bread appears on the shelf every morning. No committee ordered it. No planner calculated the exact number of loaves your town needed. Yet it is there—warm, priced, and ready.That quiet miracle is the central puzzle of modern life: coordination without a coordinator. For a century, the question of whether anyone can run an economy from above has driven one of the most consequential debates in economics and political thought. Ludwig von Mises declared socialist calculation impossible. Oskar Lange answered that planners could simply simulate the market. Friedrich Hayek reframed the entire problem around knowledge that is local, tacit, and scattered across millions of minds. Then the computers arrived—and the argument had to be replayed under radically new conditions.The Planning Problem follows that argument all the way into the age of artificial intelligence. It asks what happens when the planner has satellites, real-time sensors, planetary-scale data, and models that can process information faster than any human bureaucracy. Does the knowledge problem dissolve? Or does it simply migrate—into interpretation, prediction, incentives, legitimacy, and finally the deepest question of all: who plans the planner?This is not a victory lap for any side. It takes the strongest version of every serious position seriously, from Lange's elegant simulation to the cybernetic dreams of the mid-twentieth century to today's digital twins and alignment research. Along the way it shows why prices remain a form of compressed information that no dashboard has yet matched, why bureaucracy corrupts the very signals it tries to gather, and why an economy is less like a machine to be optimized than a living system that reacts to being planned.Clear, rigorous, and free of tribal slogans, The Planning Problem is essential reading for anyone who wants to understand what markets actually do, what planning can and cannot achieve, and why the oldest question in economics has become one of the most urgent questions about the future of intelligence itself.
