Well, that gets to the question of how we define materialism. Broadly enough, then a nonphysical soul can also be a new materialistic cause, so we do not have a disagreement.

The fundamental issue is whether the new theory, materialistic or not, can be quantitatively and empirically tested in some way. I propose the notion of the mind as a halting oracle is such a thing. And we can call it a materialistic halting oracle so we don't violate the need for purely materialistic explanations.
