In Silicon Valley, to make a device “smart” means to add internet , allowing it to collect, send, and receive data, often while learning and to user preferences. The technology industry has invested wholesale in the idea that “smart” means better, so we have smartphones. Soon enough, we’ll have a smart city: Sidewalk Labs. It is not the first smart city — municipalities around the world have smart infrastructure like artificial-intelligence-enabled traffic lights — but it might be the most . 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 with smart technologies that will use data to disrupt everything from traffic congestion to health care, housing, zoning regulations, and greenhouse-gas emissions.
