In 2035, most of humanity will live in favelas. This will not be entirely wonderful, as many people will live in very poor housing, but it will have its good side. It will mean that cities will consist of series of small units organised, at best, by the people who know what is best for themselves and, at worst, by local crime bosses. Cities will be too big and complex for any single power to understand and manage them. They already are, in fact.
The word ‘city’ will lose some of its meaning: it will make less and less sense to describe agglomerations of tens of millions of people as if they were one place, with one identity. If current dreams of urban agriculture come true, the distinction between town and country will blur. Attempts at control won’t be abandoned, however, meaning that strange bubbles of luxury will appear, like shopping malls and office parks. To be optimistic, the human genius for inventing social structures will mean that new forms of settlement we can’t quite imagine will begin to emerge.
