CITY OF HUMAN, CITY OF MACHINE

The most distinctive trait of the machine city is the lack of human beings. Other animals live within its limits. Not the rats and pigeons of human cities—the scavengers feeding on our remnants—but animals that can thrive in such particular conditions: algae on the water-cooling ponds, lichen and moss on the unadorned walls, flowering plants within the dirt that invariably builds up along the edges of the roadways and in the cracks of the buildings, and, of course, the insects that come to feed. — omnireboot.com
