This isn't a better view though. The number of Watts is not important. Biology is efficient in energy use, so what? If you tax a human brain it doesn't especially consume vast amounts more energy. I don't work up a sweat thinking. What's more interesting is if the computational "power" has parity. Deep Blue wasn't as computationally powerful as a human brain. It was specialised which is why it's not as interesting a victory as AlphaGo which is based on a more general principal.
