Los Angeles 2019: crowded, polluted, clangorous, damp, desperate and diverse. Patrol cars called Spinners carom through the canyons created by skyscrapers 400 stories tall and crumbling in the acid rain.

The rainbow billions left behind squeeze through the jammed, littered, neon-splattered streets as numb to hope as they are to the noise.
