It is not the first smart city—municipalities around the world have adopted smart infrastructure like artificial-intelligence-enabled traffic lights—but it might be the most ambitious. The project’s 200-page wish list of features is astounding. The “vision document” imagines not only the revitalization of a 12-acre plot that has sat largely vacant since its heyday as an industrial port, but its transformation into a micro-city outfitted with smart technologies that will use data to disrupt everything from traffic congestion to health care, housing, zoning regulations, and greenhouse-gas emissions. Long before flying cars, smart sensors won’t just be in our mattresses or our bidets, they’ll be embedded in the walls of our homes and the concrete beneath our feet.
