Until I read this recently, I didn't realize that the Bohmian interpretation of quantum mechanics had been successfully extended to special relativity and field theory. As even staunch proponents of the Everett "many worlds" interpretation admit, the Bohmian and Everett interpretations are observationally equivalent. So, which is preferable, a theory of one universe with non-locally interacting particles and a locally evolving wave function, or a theory of a multiverse with just a locally evolving wave function? I'm now strongly in favor of the Bohmian option.
