Good question! I think it is often a term used by IT and consulting companies to sell specific technological fixes to difficult sociotechnical challenges – but there is certainly more to it than that. Cities are complex systems with an incredible amount of coordination required for their functioning, our current solutions enable a very limited form of domain-specific coordination that happens largely within siloes. The connectivity that IT enables could take the coordination of urban systems to a qualitatively new level by realizing whole systems cross-domain coordination. For me that is what the smart city is about, using IT to enable a much more complex form of coordination required to truly manage cities as whole systems and I think that is what is required to actually deal with the massive process of urbanization that we are currently going through and create sustainable results.
