Comment Re:City within a Building (Score 0) 98
We tried a simplified version in the 60s with tower blocks. Shops at the bottom, flats on top, all the amenities anyone would need within walking distance. They quickly turned into ghettos where no-one wanted to live. Turns out that for a successful community you need space, diversity and people travelling around to interact with outsiders. Otherwise it turns into a medieval village pretty quickly.
