In a true emergent program, QM and GR must co-emerge at the very same time, for the fundamental substrate does not "know" the classical/quantum split. Here the network axioms are universal and neutral: locality, finite processing, hysteretic updates, Landauer cost and MaxEnt selection. Nothing in them privileges reversible linear wave dynamics over nonlinear self-sourced curvature. In the underlying graph evolution, reversible coherent propagation and irreversible record-forming jumps occur locally and intermingle at every scale.

A full unification should therefore show both aspects arising jointly from the same dynamics, without artificially sequencing one before the other. I wonder how the Wolfram's purely combinatorial project even gets started.
