Martin Cooper helped invent one of the most consequential and successful products in history: the cell phone. And almost five decades after he made the first public cell phone call, on a 2-pound brick of a device called the DynaTAC, he's written a book about his career called "Cutting the Cord: The Cell Phone has Transformed Humanity." In it he tells the story of the cell phone's invention, and looks at how it has changed the world and will continue to do so.
Cooper came on the Source Code Podcast to talk about his time at Motorola, the process of designing the first-ever cell phone, whether today's tech giants are monopolies, and why he's bullish on the future of AI.
