just as a smart person is not necessarily a wise person. Case in point: John Poindexter, PhD in Physics from Cal Tech, who smartly but unwisely developed a white house intranet that enabled, but eventually exposed, the Iran-Contra arms smuggling affair and led to his criminal conviction in the Reagan era.
Technology can promote a smart city, but a wise city requires mindfulness and judgment on the part of people. Often technology can work to remove this crucial human role. A smart city could be envisioned as one in which our infrastructure is so smart that humans no longer need to think about their actions - that is a smart, but unwise, city.
