The Invisible Trillion · How a Neighborhood Dies

The Highway Map

Pull back and look at where all this lands geographically, and the highway parallel stops being a metaphor.

Data centers cluster where the power, fiber, and climate suit them. But within a cluster, the specific question — which neighborhood gets the 500,000-square-foot building, which street gets the substation — is settled by the local decisions and legal tools of the last chapter. And the pattern of where it lands is consistent enough to be unsettling.

Overlay the data center sites in Loudoun County, Virginia, on a map of household income, and they sit in the working-class subdivisions, not the wealthy parts of the county. In the Memphis area, the xAI facilities are in Boxtown and Whitehaven — historically Black, long industrially burdened — not in Germantown or Collierville. Around Phoenix, the cluster is in the southeast valley, below the metro’s median income, not in north Scottsdale or Paradise Valley. The same holds in Atlanta, in Dallas, in the Intel-anchored cluster in Licking County outside Columbus.

The places hosting the noise, the emissions, the higher bills, and the truck traffic are systematically not the places whose residents own and profit from the industry — consistently enough that you could predict, with fair accuracy, where the next big facility in a metro will go by finding the working-class edge where organized resistance is likely to be thinnest.

This is the highway map, sixty years on. The Cross-Bronx Expressway did not run through Riverdale; I-375 did not run through Grosse Pointe; I-94 did not run through Edina. The decisions about where the burden fell were made by people who would never bear it, and the legal tools made it easier to drop in some places than others. The data center decisions carry the same asymmetry, with newer instruments, landing on the same kinds of places.

A generation from now, the histories of the AI buildout will include maps — red where the facilities went, blue where the wealthy parts of those metros were — and the two colors won’t overlap much, just as they didn’t for the highways. The lesson, taught alongside Caro the way it’s taught now, will be that the pattern was legible in advance. Whether it was legible early enough to matter is the part still being decided.
