J.S.Bell wrote somewhere: "I think Einstein thought that Bohm's model was too glib too simple. I think he waslooking for a much more profound rediscovery of quantum phenomena. The idea that you could just add a few variables and the whole thing [quantum mechanics] would remain unchanged apart from the interpretation, which was a kind of trivial addition to ordinary quantum mechanics, must have been a disappointment to him. I can understand that to see that that is all you need to do to make a hidden-variable theory. I am sure that Einstein, and most other people, would have liked to have seen some big principle emerging, like the principle of relativity, or the principle of the conservation of energy. In Bohm's model one did not see anything like that." It is interesting to point out that according to Mermin QM is about "correlations without correlata" (correlations have physical reality while the correlata have no physical reality). According to C.Fuchs the opposite seems to be true in MWI (being a realistic interpretation), that is to say: "correlata without correlations".
