Matt O’Dowd is a first class science communicator. In this latest video, he does an excellent job explaining decoherence, and why the MWI (many worlds interpretation) ends up being so tempting when you see it through.
Of course, this doesn’t mean MWI is the right interpretation, but it does demonstrate why many find it tempting. (At least once they get over the visceral reaction we all seem to initially have for it.)
But it’s worth noting that decoherence actually is compatible with pilot-wave and many other interpretations, and reportedly even some versions of Copenhagen. So don’t let MWI cause you to dismiss it!
