The Terafab does not swallow one terawatt of electricity.
People smash the numbers together. Current output of AI compute is roughly 20 gigawatts a year. That is chip output, not the factory power bill.
The 1 TW target is hardware you ship in a year. The 10 GW by 2027 is the power you stand up so the line can actually run.
20 GW is the planet now. 1 TW is the target. 10 GW is what you build so it turns on.
Own the photons. Then own the watts.
