This informational metaphysics may, but does not have to, endorse a more controversial view of the physical universe as a gigantic digital computer, according to which dynamic processes are some kind of transitions in computational states. The distinction may seem subtle, but it is crucial. Imagine describing the stomach as if it were a computer (with inputs, processing stages, and output) versus holding that the stomach actually is a computer. Whether the physical universe might be effectively and adequately modelled digitally and computationally is a different question from whether the ultimate nature of the physical universe might be actually digital and computational in itself. The first is an empirico-mathematical question that, so far, remains unsettled. The second is a metaphysical question that should probably be answered in the negative, at least according to the majority of physicists and philosophers. One reason is because the models proposed in digital physics are not easily reconcilable with our current understanding of the universe.
