> It's how physics is done. PhD students don't sit in physics departments getting ideas from their interpretation of QM. The interpretations people have are so meaningless and useless they never appear in physics publications.

They do if they're going into foundations of physics. There's a sociological problem where the Copenhagen interpretation won out in the past and resulted in the shut up and calculate orthodoxy in teaching physics. But there are physicists like Sean Carol who think that's a historical mistake and based on failing to think about QM correctly.

> That's the thing about most QM interpretations, and in particular the many worlds interpretation, and why they aren't science just stories: you're right, they add nothing. So they are untestable!

Some make testable predictions like the collapse theories. For the others, it's more about the proper way to understanding what the mathematical formalism and experimental results are telling us about the world, and how we can use that to advance future physics.

> What can I say to "should"? I can only report what physics is in the real world.

And there have always been physicists like Einstein, Everett, Bohm and Bell who pushed back.

People don't do PhDs on this topic because it's not productive. Famous/bored/tenured/rich people pitch in arguments for fun. Anyway, the vast majority of work in foundations of physics has nothing to do with these interpretations https://link.springer.com/journal/10701/volumes-and-issues This is a niche inside a niche in a mostly irrelevant field.

No advance in physics has ever been made based on QM interpretations. No Nobel has ever been won. No phenomena have ever been discovered this way. It's just not what people work on and it's not how physics is done.

You're determined that your view of the world is right, and that of actual working scientists is somehow blind orthodoxy that's missing the point. There's nothing I can say to fix that. It's like arguing with an antivaxer. You think you know more than the people doing the work. Bye stranger! But.. it's worth considering that here and elsewhere in life your probably don't know better.

I'm just repeating arguments that physicists like David Deustch, Sean Carrol, David Wallace, Sabine Hossenfelder have made, because they sound like good arguments to me. Better than ignoring the issues you get with shut up and calculate. Maybe you should take the issue up with them? Perhaps you think throwing out the term antivaxer makes you smarter than Einstein, Schrodinger and Bell?
This is like watching Star Trek and reading a book on the science of Star Trek where people make wild conjectures and coming away thinking that "Oh wow, scientists are working hard on warp drives!".
