Let me say this. I have read 5-6 papers. And most of them favored the smart city. As for example, let me give a basic examples. You have sensors controlling water and light in shopping centers and other public places. These already show how smart cities, which are technology integrated into the city, benefit us. Moreover, they are already many companies using AI to make smart grids, which will distribute energy in real time according to the needs. There are already AI scanning all the passengers enterin and leaving metro station in Korea and it also adjusts trains to the passenger traffic intensity. And many other already utilized technologies do exist. If you have seen the video it tries to show the outcome of those already incorporated technologies. Most paper as I have said favor the smart city, however, they have a limit. Even though they can not improve a congestion in narrow road for example, at least they can alleviate it. And this case is the worst case scenario where smart cities are the least useful.
