Nick Harkaway dismisses fears of a digital dystopia in which distracted people, caught between the real world and the screen world, are under constant surveillance. He believes we need to engage with the computers we have created, and shape our own destiny. Simon Ings is the editor of a new digital magazine, Arc, which uses science fiction to explore and explain what the future might hold for society. While Anab Jain's design company uses scenarios and prototypes to probe emerging technologies and ideas, from headsets to help the blind to see, to everyday objects with their very own internet connection.
