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.
