In 1987, I sat outside the Medco Center in Springfield, Kentucky, with my grandfather, Bob Burns, a blind ex-industrial laundry worker from Boston. At 80, Bob spent many of his final days at Medco Center, seated in a folding chair and following the sun like a human sundial. One day, he showed me a remarkable watch that, with the press of a button, would speak the current time – a fascinating device for a seven-year-old. This moment marked the beginning of my curiosity of how technology could change everyday life, and the start of my journey in what is now called decentralized physical infrastructure (DePIN).
