Don't throw out realism so easily. Ending the quest for answers by invoking mysticism is very easy for people to do but its never the right answer. https://www.lesswrong.com/s/5uZQHpecjn7955faL/p/6i3zToomS86o...
I said "in my book" for a reason. You might of course argue that the wave function is real, which would make the Copenhagen interpretation a realistic, albeit non-local theory (as the collapse of the wave function would happen instantaneously everywhere). I'd be very happy to discuss this but please bear in mind that this was not what the discussion was about.
