Human brains are the most efficient at some problems. This is trivial to demonstrate: try multiplying two 10 digit numbers in your head. Now pick up a calculator and do the same in a fraction of time, using a fraction of power, and with perfect accuracy.

Computers are better than humans at some problems but I'd argue that this is because they can use their available computational powress much better than human brains can, even if it's much less. Computers are still much worse at driving cars for example and their power consumption is a real problem. If you could have done more computations for the same power budget, or with a power budget of tens of kilowatts, the problem might be solvable.
