Another mind-boggling thing about brain is how little power it uses to do all the complex things it does.

calories are a unit of energy, so it’s a straight forward comparison

if we assume that a computer can be powered by 100 watts, over a day it will use 2.4 kW h, which is about 2000 Calories

GPU will consume a lot more, but we aren’t that far off in efficiency

Doesn't that assume 100% of a human's daily calories burn is due to brain activity?

The brain uses about 20% of a human's calories. It's not 100%, but it's a substantial fraction.

The other components of the human body are also required for brain function.
