Tariffs won’t save America’s economy—but knowledge might. In the third episode of our Trade series, Nick and Goldy sit down with physicist César Hidalgo to explore how prosperity really grows—not through tariffs or trickle-down promises, but through the accumulation of knowledge and know-how. Hidalgo explains why digital exports don’t show up in trade data, why tariffs fail, and why the future belongs to countries that invest in research, strategy, and human talent.

César Hidalgo is the director of the Center for Collective Learning, with offices at the Toulouse School of Economics and Corvinus University of Budapest. A physicist by training, he is also the founder of Datawheel, a company specializing in data visualization and distribution systems. Hidalgo is the author of Why Information Grows, a groundbreaking book on the relationship between knowledge, innovation, and economic prosperity, and his forthcoming book, The Infinite Alphabet and the Laws of Knowledge, explores the dynamics of how knowledge evolves and diffuses globally.
