> When people ask for new testable predictions as the only way a new theory can be successful, they are revealing that they don't consider parsimonious explanations to be a scientific goal.
It doesn't have to be new testable predictions, but it should at least reproduce some testable predictions of the conventional theories.
As far as I know, these discrete graph models have been shown to reproduce some broad features of QM and GR (mostly the work of Jonathan Gorard rather than Wolfram), but they don't make any actual numerical predictions, which in my view is a basic requirement of a physical theory.
At the moment it seems like some intriguing toy models, similar in many respects to t'Hooft's cellular automaton model of QM, but there's no physical theory here
