I just wanted to contribute by saying that in one of his lectures (I cannot remember the exact name), Feynman said that it is important for a physicist to know many interpretations that give the same predictions but are different computationally. The simplest example that comes to my mind is Newtonian and Lagrangian mechanics. I do not know which one is simpler in the technical sense of the word, but I am sure that every physicist is expected to know and understand both of them.
