Great analogy.

It's not a good analogy at all, because of what they said about mundane hardware. They're specifically not talking about any kind of ridiculous wattage situation, they're talking about single GPUs that need fewer watts than a human in an office to make text faster than a human, or that need 2-10x the watts to make video a thousand times faster.
