The Device That Ate the World

In January 2007, a man in a black turtleneck walked onto a San Francisco stage and pulled a sliver of glass and aluminum from his pocket. Within a decade, more than half of humanity would carry its descendant everywhere they went — a camera, a map, a bank, a library, a television, and a telephone fused into one object thinner than a pencil. But the smartphone was never a single invention. It was the meeting point of a dozen long, separate stories: the cellular network dreamed up at Bell Labs, the tiny low-power chip designed for a doomed British computer, the touchscreen that finally worked, the battery chemistry that made it portable, the software store that turned a phone into a platform. E.B Cohen braids them all together — from Alexander Graham Bell to Andy Rubin's secret robot, from the IBM Simon that arrived fifteen years too early to the folding, AI-driven glass of today. This is the full story of how a device conquered the human pocket: the geniuses and rivalries, the factories and rare earths, the trillion-dollar app economy, and the harder questions about attention, surveillance, and what we surrendered in exchange for a world in our hands.
