"Enormously inefficient perhaps from an electronic engineer's point of view, but remarkably capable,of that there is no doubt."
Actually, the brain is pretty efficient, even from electronic engineer's point of view. What is noticeable about the comparison between the brain and the computer is how slow the various processes in the brain are. This is counteracted, however, by the complexity and richness of each neuron, compared to each transistor.
I've heard the brain described as "massively parallel".
