“Sustainability is becoming more and more at the forefront of everyone’s minds!”

This is simply double-talk. Indeed, there is no real content in this whole paragraph.

We can do that much more efficiently once we can track the movements of residents within cities, and once we can map which areas we can use to improve the density of cities.

Tracking the movements of residents within cities does not require AI, and is undesirable. Mapping that data doesn’t require AI either. AI isn’t just “a thing a computer does”.

Increasing the density of cities doesn’t increase their sustainability past a certain point, and indeed decreases it as, e.g., harried NY, LA and SF residents learn to rely on “ridesharing” instead of public transportation. And increasing the population density definitely degrades the local environment for those people who actually live there.

Overall, advocating for increased city density in order to increase sustainability is a bizarre idea. Surely it is the sparsely populated suburban and rural areas of America, areas whose climate footprint per capita is several times that of a city, which could benefit from increased density!
