imagined future worlds in philosophy, literature, art, film, TV and computer games. He shows that futures are often contested and saturated with different interests, especially in relation to future generations. He also shows how analyses of social institutions, practices and lives should be central to examining potential futures, and issues such as who owns the future. The future seems to be characterized by 'wicked problems'. There are multiple 'causes' and 'solutions', long-term lock-ins and complex interdependencies, and different social groups have radically different frames for understanding what is at stake. Urry explores these issues through case- studies of 3D printing and the future of manufacturing, mobilities in the city, and the futures of energy and climate change.
