My understanding of QM is quite good for someone who has never done the actual math
And my violin skills are quite good for someone who has never done the actual playing.
However, this debate is not about the equations of QM per se, but about the measure theory that tells you how “real” the different parts of them are.
Different parts of what? Of equations? They are all equally real: together they form mathematical models necessary to describe observed data.
Which is why we’re using terms like “reality fluid”.
Eliezer is probably the only one who uses that and the full term is “magical reality fluid” or something similar, named this way specifically to remind him that he is confused about it.
I have a related degree, if that’s what you are asking.

I’m yet to see anyone writing down anything more than a handwaving of this in MWI. Zurek’s ideas of einselection and envariance go some ways toward showing why only the eigenstates survive when decoherence happens, and there is some experimental support for this, though the issue is far from settled.
Precisely; the issue is far from settled. That clearly doesn’t mean “any handwavy speculation is as good as any other” but it also doesn’t mean “speculation can be dismissed out of hand because we already understand this and you’re just wrong”.

I have actually done the math for simple toy cases like Bell’s inequality. But yeah, you’re right, I’m no expert.
(Out of curiousity, are you?)
