It doesn't seem like many people are envisioning the future to be anything but a dystopia. From a complete lack of privacy (thanks to Facebook for starting the trend?) to the way cities are built with new ones being built from the internet up.
Because of the huge and detailed information collected by internet of things (IoT) devices, smart city projects could lead to similar worries. Take for example, the Cityware project, which demonstrated the possibility of mapping not just digital but also physical encounters between Facebook friends. Cityware were able to track the movement and interaction of 30,000 people using their Facebook profile and smartphone bluetooth signals.
