In "prescient article" in the journal Significance futurist James Canton argues that cities will diversify as they get larger, writes Michael Batty on his A Science of Cities blog.
Megacities will become the primary form for future urbanization, Canton argues. The growth of the new megacities may ultimately only be constrained only by the ability of a single government to manage them. Canton lays out several possible models for the new megacities, such as Chaos City (think Mogadishu) to Gang City (think Afghanistan), Fortress City (think Dubai) and the Smart City.
From Canton's article:
"By 2040, most of the world's population will be living in megacities, writes Canton. A megacity is a city containing at least 10 million people. Megacities already exist. There are as many as 26 of them on the planet today...
"The Smart City is coming and the megacity will bring it soon. The actual development of artificial intelligence as an incentive to meet the challenges of the Smart City will set the stage for the future. Nine billion people will be the largest concentrations of human density in the history of civilisation. Some find it almost impossible to imagine it all turning out well... What planners, policy-makers, leaders and social scientists should be doing today is getting ready with new models of planetary management. Our lack of readiness for the future is endemic in our civilisation. But it would be good to get this forecast right and prepare for the megacity future."
