Cities all around the world have set the same goal for themselves. Amsterdam, Barcelona, Birmingham, Dubai, Helsinki, San Diego, Stockholm, Nanjing, Vienna, Yokohama -- they all share an aspiration to become "smart cities."

That sounds like an appealing aim, yet when urban planners try to explain more precisely how they plan to lead their cities into the digital future, their answers are less convincing, with each proposing a different plan. Despite the many symposiums that have been held on this subject, there is no consensus on how to pursue this ambition.
