Here is my bottom-line assessment of the Wolfram Model:
Suppose one were to take a canonical (whatever that is) formulations of GR (Einstein field equations) and QM (quantum field theory / path integral formulation) and (re)present then in the *Python *language (or your favorite cool language, like *Haskell*) - one that has automatic differentiation / differentiable programming libraries - just as done in numerical relativity, cosmology, quantum mechanics - one would not get much more "interesting" (or useful) than the *Wolfram Model*. In fact it may be more interesting and/or useful. @philipthrift On Saturday, May 2, 2020 at 5:48:51 AM UTC-5, Philip Thrift wrote: > > > > > *Some Quantum Mechanical Properties of the Wolfram Model* > Jonathan Gorard > > One intuitive interpretation of the evolution of a multiway system for a > non-causal invariant system, and therefore one in which distinct evolution > branches can yield non-isomorphic causal graphs, is that the system is > evolving according to every possible evolution history (i.e. all possible > updating orders), any pair of which may have observationally-distinct > consequences.
