“It turns out that most of the … mishaps [in nuclear plants] actually involve humans. So we were thinking today, what do we do to create a power plant control system to minimize that kind of impact? We came up with the following. The power plant of the future will have three control devices: a computer, a dog, and a guy. The computer runs the power plant because, as I said, most power plant mishaps happen because of human interaction. The dog keeps people away from the computer. And the guy is just there to feed the dog.”
