I believe we have quite reasonable understanding on quantum mechanics and much more. Many questions on deeper meaning of quantum mechanics seem too philosophical to the point of almost becoming meta-physics. However, deep thinkers who care more about foundations of physics find it less satisfactory. Asking why has always been the start of new discoveries and new theories.
First rate physicists always ask why and find answers. This is usually how new physics is developed.
Path integral is one way of denoting and calculating interactions of particles. It is convenient and it does its own book-keeping. But I don’t think it reveals anything deep about nature. It is only one of many schemes of doing calculations. But of course Feymann would disagree.
I subscribe the God of Einstein. The beauty of physical laws is much more attractive and revealing to me than pure theology questions.
