GPS is the rare piece of infrastructure most of us never think about until it fails — and it is failing more often, in more places, by design. In Little Blue Dot: How GPS Shaped the Modern World, journalist Katherine Dunn traces the system from its Cold War origins — wartime radio beams, Vietnam's precision-bombing problem, the Soviet shock of Sputnik — to its current role underpinning modern life, governing not just where we are but the precise time that keeps power grids, markets, and supply chains in sync. Chris talks with Dunn about how a taxpayer-funded military tool became invisible civilian scaffolding, and how it turned into a battlefield: Russian jamming and spoofing from the Black Sea to the Baltics, ships that appear at airports, a drone war fought over the electromagnetic spectrum, and what it means when certainty itself becomes a target.
