" A city is half beast and half machine, with arteries of fresh water and veins of foul, nerves of telephone and electrical cables, sewer lines for bowels, pipes full of pressurized steam and others carrying gas, valves and fans and filters and meters and motors and transformers and tens of thousands of interlinked computers, and though its people sleep, the city never does. "
