Can you explain what the direct and practical implications are?
I don't know if I buy what the link says about this, but I do know that no one has ever found utility by being frustrated about many worlds
I mean that interpretations have practical implications because they're the only way to find the true laws of physics, which in turn has obviously applications. For example, if you believe in superdeterminism, and you obviously should, then that will save a lot of work researching dead ends (like multiverse stuff), which will make us find the correct algorithms faster.
