Actually, I think information theory is the only branch of science that has something genuinely useful to say about computers. Unfortunately, it has few people working on it in the context of computer systems. The world is dying for useful models of (real) CPUs and complex networks based on information theory, but that's not really happening. Computer "scientists" rather spend their time building example systems that no one will ever use, or creating theoretical models that have no connection to reality. No idea what the purpose of either is.
