Then at the very least, you should be able to simulate a biological brain, neuron by neuron, and get an intelligent computer that way. If you agree that's possible, you also have to consider whether it's the most efficient approach -- plausibly special algorithms could be invented that get the same intelligence at a fraction of the computing power.
