Maybe, maybe not. I'm not sure if it's just a matter of scale or of the fundamental nature of the thing. It might be that the computer / neural network metaphor, whilst isomorphic to certain brain procesees, may ultimately not tell us very much about the larger system and what it actually is. I tend to think that because computers are the current peak of civilisation / engineering, and in some ways, "alive", we think we might be like a computer. In the Victorian machine age they talked of humans as machines. Maybe some, hitherto unthinkable invention is around the corner, and we will say humans / brains are like that too.
