CONCEPT
Infrastructure Dependency
The unseen foundation beneath every AI interaction — fabs, power plants, data centers, supply chains — whose concentration and opacity create a tenant-landlord relationship between users and providers that the democratization narrative systematically obscures.
A smartphone is a magic trick. A flat rectangle of glass and metal that responds to touch, connects to the sum of human knowledge, navigates by satellite. The user sees the trick. The engineer sees the infrastructure: cell tower, fiber-optic cable, switching station, continental backbone, transatlantic cable, data center, power plant, fuel supply chain, and — behind all of it — a semiconductor fabrication plant that cost fifteen to twenty billion dollars to construct and employs thousands of engineers in cleanroom conditions more stringent than a surgical theater. The AI tools Edo Segal celebrates in You On AI sit on infrastructure comparable in scale and complexity, and the infrastructure behind the smartphone took decades and trillions of cumulative investment to build.

The training infrastructure comes first. A frontier language model requires clusters of thousands of specialized processors — GPUs or TPUs — connected by high-bandwidth networks and powered by dedicated electrical substations. Training a
