Well, if you look at them from very far and keep your ears closed they kind of resemble birds. And they do resemble birds more than other stuff in the air. I think that analogy probably will hold up; the eventual strong AI will resemble a brain a complexity and will have a lot of things in common, but it will not be the same.
Well, no. You're right. I don't know whether that invalidates my point though. It may not be necessary to model the human brain to achieve machine intelligence. It may also be that any sufficient machine intelligence would wind up modelling the human brain to a limited but necessary degree, in a similar way that birds and airplanes share wings with similar lift effects, but different mechanics. Until there's something real to point at, I think it's semantics.
