In both comp and the quantum, a case can be made that the
irreversibility of memory (coming from usual thermodynamics, or big
number law) can explain, through physical or comp-physical
interactions, the first person feeling of irreversibility.
But with comp we do start from a basic "irreversibility": 0 has a
successor but no predecessors. And we do get physical symmetries
(perhaps not enough: open problem), and then we get a temporal logic
directly from the theaetetical definition of the first person (the

I don't understand.
