“How Does a Smart City Get Smarter”?
This is the new challenge for the Information and Communication Technologies. Remaining at the “ground level”, let us consider the state of the art and ask: how does a city get smart?
There will be smart trees for the sidewalks of the smart cities?

Even the smart cities requires smart administrators. Likely the tree in picture was there before the sidewalk building.
The administrators, right. This is a good point that brings us back to SM2. Are the administrators educating the inhabitants or vice versa?
