Do you really think there's more to the human brain than a more-complex version of a computer? I think we've all established that the brain is a network of neurons with different structures that do different processing and that the neurons work in a specific way to turn sensory inputs and memories into thoughts and actions. We don't know everything about the metaphysical aspects of how the mechanics turn into "consciousness" but we pretty much know that we could, with a powerful machine, simulate most of the mechanics ourselves. Maybe an AI isn't as complex as our biological computer, but that's because our AIs run on computers that are only several dozen generations in, versus our brains which are several million generations in. Perhaps in several million generations of our AI hardware and software, we'll come up with something as computationally powerful as our brains.

I don't think we know any of that. We know many of the mechanisms through which neurons act but not all of them, nor do we know that we can simulate a human brain on a computer.
