I think there will be some kind of cities-skyscrapers.
In a nutshell, this will be a highr-rise building. I imagine: in one giant skyscraper, you can see shops, hairdressers, offices, restaurants, various entertainment zones and much more. Up to 100 000 thouthands would live in such building. For many people, there will be no need to leave the building.To buy the necessary products, for example, go down to 20 floors, for going to work - go up to 7 floors. A full life can be kept without leaving the skyscraper.
