Although this does not have much bearing on the general discussion, it should be said that the story about Einstein seems very doubtful. He died in 1955 and Bell's paper only appeared in 1964. Moreover, Bell's work is theoretical: it could not "prove" anything about the real world, except the fact that something was testable, in principle. Einstein, if he had been alive, could very well have said that he expected experiments to go one way instead of another. And the actual experiments came quite a bit later.
