Considering we've already simulated the basic building blocks of our brain and understand all the basic molecules involved, I'd say that we already have a very strong indication that we can eventually have a machine conciseness similar to our own. The only two physical process that we know of that are fundamentally impossible to compute with our computing model are quantum computations and chaotic systems. And for chaotic systems we most certainly can simulate them in a way that the output has all the correct properties as far as we know. It's more that we can't reliably do prediction in such systems due to finite precision. The simple fact is that computers are already our superiors on many tasks. And those tasks are not simple either.
