Obviously we're discussing faith and intuition here, as none of us has the facts. I don't think there is anything computationally irreducible in the brain. About some component not being expressible as the result of simpler computations: that has to happen at some point, by definition. But that point is probably within the reach of our understanding. All in all, I don't think there is much magic, just lack of knowledge on our part. Of course, it's just my intuition.
