Need to specify types of approaches
I agree with much of the thrust of the article but it is important to clarify what types of smart cities and approaches when comparing cities from other countries ( e.g. China and South Korea). There are greenfield smart cities ( which tend to be in developing nations and start at a new master planned level often ) and brownfield cities ( which really are focused on precinct scale development within existing cities or smart initiatives within certain industry sectors ). It is therefore a little misleading to simply compare a transport initiative in New York for example to a massive new smart city development in China as they are fundamentally different. Thus, a like with like comparative approach, when explaining smart city issues worldwide, in my opinion, is required and will help to ensure better understanding within this topical area of debate.
