In 1981, in a Utopian literature class at the Univ. of Hawaii at Hilo, I read a book that haunts me because of its prescient look ahead. People live in sealed homes, connected digitally by video and audio to interact with friends and clean versions of the world outside. The interior walls of homes fill up with these images. A kind of solitary confinement no one seemed to mind. Food and goods were delivered to homes through portals by a working class of people exposed to a toxic world outside. I don’t remember details beyond that except that it was written by a man. My online searches for it have failed me!
