The Compute Empire
The first center that is not a city.
Kernel
The plausible 2035 successor to every center in this archive is not a city but a distributed infrastructure: 200,000-GPU training clusters in Phoenix, Memphis, Inner Mongolia, the Gulf, Pori, the Hebrides; the agent-economy interfaces those clusters expose; the legal and capital structures that own them. If the 21st-century pattern holds — and it might not — the "center" of civilization for the next several decades may be the polity that owns the most compute.
What it could look like
The Compute Empire is structurally different from every historical center: it is not a city, it has no commute, it has no marketplace, it has no agora. Its visible surface is regulatory and capital — which jurisdiction it incorporates in, which sovereign signed off on the next training run, which AI lab's safety case the regulator accepted. The cathedral-as-data-center essay applies: this is a center organized around producing artifacts, not around housing citizens.
Where it might fail
Concentration risk. If compute centralizes around a small number of vendors and jurisdictions, the resulting fragility is comparable to the 17th-century Dutch peat industry — one shock and the substrate collapses. Decentralized alternatives (local inference, open weights, agent-to-agent commerce) may erode the empire faster than centralized infrastructure can extend. The history of every center in this archive suggests the empire phase ends.
