Another way of thinking about how efficient the brain is: By the article’s numbers, about 5.5 million TPU hours were required to train the machine to play as well as a Go champion.<p>A Go champion might have trained for 8 hours a day, for 15 years (age 5 to 20). That is about 40 000 hours.<p>In other words, machines required 137 times longer to learn the game, and at twice the power consumption! There is still a lot of room for improvement.
