What we cover

Seven layers. One job: get compute online.

None of these works alone. A chip is nothing without power, power is nothing without a crew to build the plant, and nobody builds without the money to pay for it. We look at how the layers fit, and where they come apart.

  1. AIThe demand. What the models need, and what software really changes on a jobsite.
  2. EnergySpeed to power. Transformers, utility connections and on-site generation.
  3. InfrastructureThe grid, the water, the roads and the sites that have to exist first.
  4. ConstructionThe trades and the schedules that turn a press release into a building.
  5. TechnologyThe tools that help the field, and the ones that only write the problem down faster.
  6. ManufacturingThe gear. Who makes it, how long it takes, and what happens when it doesn't ship.
  7. InvestmentThe capital behind it all, and what it takes to keep the money confident.
