A major revolution, comparable to the invention of gunpowder or the nuclear age, is transforming the way wars are fought. Thanks to the Defense Innovation Unit (DIU), technologies from Silicon Valley—such as intelligent drones, flying vehicles, and surveillance microsatellites—are rapidly joining the U.S. arsenal. Created to bypass the Pentagon’s bureaucracy, the unit serves as a bridge between tech startups and the military. Shah and Kirchhoff recount this unprecedented alliance that is redefining American military power, at a time when China requires its companies to share their research with its armed forces. In this tense geopolitical climate, strengthening ties between Washington and Silicon Valley is no longer optional—it’s a strategic necessity.
