## Quote — verbatim

> I think by 2028 or 29, we'll need a gigawatt data center to train the latest AI. A gigawatt data center is a nuclear reactor... And we know that's not sustainable. We can't build nuclear reactors fast enough.

## Context — site annotation, not spoken

Explaining why centralized training scaling (energy need doubling ~every 2 years) breaks down, setting up distributed training as the alternative.
