 The first point is relevant once we compare digital computation with the idea of a computer working with real numbers in continuous time. It has been proved (see C. Moore 1996) that such a device would be able to compute more functions than a traditional Turing machine. However, proponents of a discrete space-time like Wolfram treat continuous processes as, in a sense, epiphenomenal, since they already have independent reasons (some of which will be addressed  below)  to believe in a fundamentally discrete universe. As for the second point, its main problem is that the interpretation of “equivalent sophistication” is not straightforward. For even assuming that universal computation is widespread, it does not seem to follow that all computation is equivalent in sophistication. Complexity scientists, even after having agreed with Wolfram on the importance of computation for social, biological and physical systems, and even on the extent to which universal computation is supported in nature, are puzzled by his claim:
