The big cities of the 21st century are now becoming even bigger. They continue to grow out of control due to a constant expansion that reduces the rural green areas still available. It is a problem that already affects the entire planet and contributes to its drastic climate change. The concept of the digital and intelligent city of the 21st century offers an alternative to mitigate this problem by promoting the adoption of information and communication technology (ICT) to rationalize this peripheral growth, optimizing the use of the central space of any city. In the case of Mexico City, how feasible is the mentioned technological adoption by the respective population? This research-based work answers this question.
