IMO this makes no sense and is utter fear mongering. We're talking only 14 years between now and 2030. A vision of what "megacities" and the likes is pure garbage. The only thing that will change drastically in 2030 is society at the core, when millennials reach adulthood.

Pentagon Video Warns of “Unavoidable” Dystopian Future for World’s Biggest Cities

'At least that’s the scenario outlined in “Megacities: Urban Future, the Emerging Complexity,” a five-minute video that has been used at the Pentagon’s Joint Special Operations University. '

'A 2014 Army report, titled “Megacities and the United States Army,” warned that “the Army is currently unprepared. '

' The future is urban.”'

'But that doesn’t mean the future is a total unknown. '

'According to a startling Pentagon video obtained by The Intercept, the future of global cities will be an amalgam of the settings of “Escape from New York” and “Robocop” — with dashes of the “Warriors” and “Divergent” thrown in. '
