'We cluster in cities' Parag Khanna, CNN global contributor and author

Geopolitical futurist and author of Connectography: Mapping the Global Network Revolution, Parag Khanna believes we are living in a world in which megacities, supply chains and connective technologies are redrawing the map away from borders and states: “If an alien observed the human species from the last 100,000 years, they would only have two things to say that are true across all societies. We, the 8 billion people, try to live near water and we cluster in cities.” Archive talk recorded at The Marketing Society London conference.
