AI Deflation: The New Railway Crash?

Aug 6, 2026 · 36m

Summary

David McWilliams argues that the AI boom is a speculative bubble akin to the 19th-century railway craze, driven by crowd psychology rather than fundamentals. He predicts that AI’s deflationary impact on wages, combined with record global debt, will trigger massive defaults and bankruptcies among major tech firms. Using South Korea as a warning sign, he foresees a debt-deflation vortex similar to the 1873 crash, where falling incomes make existing debt unsustainable.
