I wonder what cities will look like in thirty years. With the advent of work-from-home, school-from-home and delivery drones, people literally won't need to leave their residences. I could see fortress-like blocks/buildings where people live in relative safety for almost their entire lives, with enough walled-in common amenities to provide some community outside their personal living space (e.g. a park-like area, a few cafes/restaurants). When they have to travel, it might be by air taxi off the roof. Outside, squalor and feral blacks who no one will bother to police.
