How Physics-Based Simulation is Turning Cities into Planetary-Scale AI Chips

What if a city is becoming the AI chip of the Earth?

• Buildings are its transistors.
• Roads are its interconnects.
• People, vehicles, air, heat, water, and energy are the data continuously flowing through it.

But unlike a silicon chip, a city does not run on digital signals alone.

It runs on physics.

To understand and optimize this planetary-scale processor:

We need to simulate every interaction—from terrain and wind to human movement and infrastructure.

If cities are becoming the intelligence layer of our planet, can we truly make them smarter without first understanding their physics?
