A few AC is one thing.

Many AC in a limited space covered in concrete with almost zero tree in the area is another thing.

We need to be more specific about what we are talking about.

Anyway ACs are not enough in a city. ideally you also want streets with a significant amount of trees and greenery so that there is significant shade and heat from sunlight doesn't radiate too much from concrete/pavement.

They're also missing the winter bit, where an AC heatpump needs three ou four times less energy than a resistive heater ... oh well.
