The dissolution of the barrier between the public and the private, the sense of being surveilled and judged, extends far beyond human observers. We are also being watched by the very devices on which we make our broadcasts. As the artist and geographer Trevor Paglen recently said in the art magazine Frieze: “We are at the point (actually, probably long past) where the majority of the world’s images are made by machines for machines.” In this environment of enforced transparency, the equivalent of the Nighthawks diner, almost everything we do, from shopping in a supermarket to posting a photograph on Facebook, is mapped, and the gathered data used to predict, monetise, encourage or inhibit our future actions.
