This is a moment to be savored, even as we sound new notes of care and caution about the speed, nature and range of these changes. Part of this process involves getting used to the alien nature and pervasive reach of the many new subintelligences that now surround us. These are the algorithms that talk with us, that watch us, that trade for us, that select dates for us, that suggest what we might buy, sell, or wear. They are the algorithms that pool information about us, and that will slowly permeate the full range of human-built environments, from bridges to roads to cities and more minor intelligent devices.
