Indeed this seems an important empiricial result, ruling out certain classes of models, including, dare I say, Wolfram's NKS. However, it does not rule out computationalism, nor the countability of observer moments, as I've point out many time, as space-time is most likely a model construct, rather than actually being something physical "out there". It is something Allen Francom bangs on about too, which I tend to agree with, although admittedly I've gotten lost with his Brownian Quantum Universe models.
