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.
