Physics in general, and quantum theory in particular, began as the study of objective reality, i.e., a reality that exists whether or not it is being observed. Classical physics had no problem with this approach. When classical physics proved inadequate to the task of explaining the results of certain experiments, quantum theory arose. It was spectacularly successful in explaining these results and many more, too. Then a few physicists began to ask, is this all that quantum theory means–the explanation of experimental results? Does it have any ontological value, i.e., can it tell us what objective reality _is, not just what it does? This is what an interpretation _of quantum theory is supposed to do, to describe what objective reality is. So a few physicists worked very hard to come up with an interpretation in terms of an objective reality….and failed. But the failure was that there were too many contenders, not too few, and there was no way to determine which one, if any, was correct. Furthermore, most of them pretend that the quantum wavefunction, which is a probability wave rather than a physical wave, is an objectively real object rather than being simply the mathematical formula that it is. However, rather than this being cause for despair, it actually can liberate us from the prison of objective reality. As long as we believe that objects are real, we will find it difficult to escape the belief that we are objects, and consequently to feel separate from all other objects.
