Civic systems chattered away. The sidewalk slabs beneath his feet fed a steady stream of counts of passers-by, estimates of weight and height and gender, plots of probabilistic walking paths, data collected for the city planners. Embedded biosensors monitored the trees lining the street, the hydration of their soils, the condition of their limbs. Health monitors watched for runny noses, sneezing, coughing, any signs of an outbreak of disease. New York City’s nervous system kept constant vigil, keeping the city healthy, looking for ways to improve it.
