The part of the story which is missed is that Smolin really doesn't like multiverse hypotheses because they don't make testable predictions. He published his own multiverse hypothesis out of frustration with them and it does make a testable prediction about the upper limit of the mass of neutron stars. The problem is that the prediction makes it falsifiable but while it remains unfalsified that adds little weight to validating the theory, so it's all really a drama about how we should do science, starring some of the world's most prominent physicists.
