A theory of physics is mathematically quite similar to a cellular automaton. This theory will usually be incomplete, something that we can represent in infra-Bayesianism by Knightian uncertainty. So, the “cellular automaton” has underspecified time evolution.
What evidence is there that incomplete models with Knightian uncertainty are a way to turn rough models of physics into loss functions? Can the ideas behind it be applied to regular Bayesianism?
