Hi Marcel,
Thank you for the comment. Answering your comment, Philosophy is about knowing everything there is to know and not about specific concepts. Anyway, I tried to use as little concepts as possible in my argument. It does not matter what Reality is made of, it might me composed of matter (black and/or regular) energy (black and/or regular),strings, ghosts, monads, substances, causes, or any other concept we might think of. What it matters is that we won't be able to prove that Reality is Analog or Digital because we could always doubt the latest technological results. Just check what happened with classical physics, relativity, and quantum mechanics. We are always experimenting and finding cracks in the theories to test their limits. Even if we find a theory that unifies all forces (The Force?) Quantum Mechanics and Relativity, we will make experiments to find cracks in such theory. This constant process of constructing theories and making experiments to prove these theories right or wrong is what makes science fun.
