Wolfram 2002 argues that spacetime may actually be a discrete causal network and writes:
The idea that space might be defined by some sort of causal network of discrete elementary quantum events arose in various forms in work by Carl von Weizsäcker (ur-theory), John Wheeler (pregeometry), David Finkelstein (spacetime code), David Bohm (topochronology) and Roger Penrose (spin networks; see page 1055).
Later, in 10.9, he discusses using graphical causal models to fit observed data using Bayes’ rule. I don’t know if he ever connects the two points, though.
Few words: CPT symmetry. The causality is just how we model things at macroscopic scale where the time symmetry is broken thermodynamically. At the bottom level, it’s relations that have to be true, and to say that value of one variable in a relation causes value of other variable in a relation is either a minor language misuse or a gross misunderstanding arising from such misuse.
