I think at any level level of reasoning where you compare computer science and physics they become pretty indistinguishable. At that point it's all about which words you use to describe it. Some pretty important ones seem to be: entropy, energy, information, logic, and computability. Those seem to sit squarely between information theory, physics, and math. I think what this debate really means is that we're not yet going to find some sort of nice hierarchy where every result in chemistry can be considered a practical simplification of something squarely in physics. Instead perhaps both physics and CS are attacking a problem so fundamental that eventually there will be a new body of study that considers both CS and physics both to be a practical simplification of its results. Exciting, no?
