Well, thanks. But I am not quite sure why you say this. Normally the quantum 
physical explanation should be recovered from “comp”, but we are far from this. 
In arithmetic, the interference must come from the fact that we (the universal 
machine) have no means to distinguish the computations which differs below our 
substitution level. Somehow, if the path of an electron does not change our 
mind state, then we must sum on all path, which leads to an explosion of 
possible histories. Fortunately, the self-referential correctness imposed some 
quantum, or quantum-like, structure on such sets, and intuitively we can hope 
to get the Feynman phase randomisation to diminish the probability of 
“aberrant” histories, but I doubt we can get that directly from the comp 
intuition, and much progress must been made on the "logics of matter” imposed 
by incompleteness (that is the logic of []p&p, []p&<>t, …, with “p” 
semi-computable. I just hope the arithmetical quantum logic(s) to be 
constrained enough so that Gleason theorem will be applicable, in some “normal” 
future(s). If that is shown impossible, then we will have evidences that “comp” 
is false, (or that we are in a Bostrom-like malevolent simulation but this is 
trivial and can be added to any experimental verification (ultimate epicycles).
