The context of this thread is the cost of training brains and models on comparable tasks. Not that the model is comparable to a human in every way. If you want to be pedantic then 6% of the human brain is the visual cortex but then you also have to argue that AlexNet is horribly inefficient to train. So you cut the brain cost to 6% and the model cost to 1%. They're still within an order of magnitude (favoring the model) which I'd say is pretty close in terms of energy usage.
