FT Article Sparks Debate: Hayek's Insight Is Not Just Dispersed Info—Markets Generate It

AndyMasley, citing a recent FT article on AI and central planning, points out that most discussions miss half of Hayek's core insight: markets are not merely a mechanism for collecting the information an economy needs—they are also where that information gets generated.
The Substack piece he cites, "I Misunderstood Hayek," develops the argument:
- Hayek's classic view is that practical knowledge is widely dispersed across society, with no one holding complete knowledge—the author uses "making a peanut butter sandwich from scratch" as an example: domesticating wheat, building farm machinery, producing fertilizer... no single individual possesses all the expertise involved
- But the author argues his initial understanding was incomplete: information is not only distributed across markets, it is also produced by the market process itself—much knowledge and many innovations only come into being through market exchange and price signals
- This distinction is crucial to today's debate over whether AI can replace markets for central planning: if markets themselves generate information, merely having AI collect and aggregate existing data cannot replicate the market's full function
