I studied lots of points of view, and lots of how physicists actually use quantum mechanics in the applications. I came to the conclusion that there is an objective and a subjective side to quantum mechanics. The collapse belongs to the subjective side, since it is associated with ''knowledge'' of which nature is ignorant. ''shut up and calculate'' belongs to the objective side. it couldn't work if the collapse were indispensable. Properly distinguishing between an objective and a subjective side clears up a lot of the confusion prevailing in the foundations of QM.
