Amplify the above statement.Even Zurek, who starts from a many worlds perspective, thinks that ultimately one can abandon the non-seen worlds as irrelevant.
But when, exactly do they get to be "unseen". Decoherence theory has given a pretty good answer to that. And Zurek's quantum Darwinism has at least outlined a stat-mech answer to the basis problem.
