It is true, more and more of us live in big cities with infrastructures at a mega scale, some sophisticated and others barely functional. Buildings of steel and glass. Wrought iron bridges. Fossil-fuelled power stations generating electricity invisibly traversing great distances, passing through immense transformers and pylons. Train tracks connecting discrete points across the land. Powerful engines shuttling us in vehicles through the landscape on autobahns. And yet we elude our physical surroundings as we interact with the world and each other via ephemeral images on LED backlit glass and we cut out the din of the city streets with an audio book on earphones.
