>The most sensible explanation I've heard came from sir Arthur Eddington. His claim (roughly) is that probabilities in quantum theory model our knowledge of the quantum system, rather than indicating anything intrinsically probabilistic in the system itself.
That's counter to a century of experiments and theories. If that was the case, QM would be a trivial classical theory.
The pilot wave does all the work of physical reality in that interpretation. Imagining there is this extra downstream classical reality is just a bunch of extra work for no benefit, and should be discarded per Occam.
