At the most basic level reality is a discrete digital particle arithmetic with no need for further calculations in a block universe.
At a higher level it is analog in the realm of quantum waves and fields including the electromagnetic field and perhaps some bosons And at the highest/physical level reality goes back to particles/fermions yanniru.
