The short answer is that while we know QM is incomplete, we equally know that it all has to add up to normality—meaning among other things that QM results, including the weird ones, have to be explainable by the underlying mechanics.
This is not an answer. We need explanations for observed events, to be sure, but it’s far from clear that we need QM explanations. After all, buying the QM explanations of the observed events means giving up all the GR explanations of the observed events.
We’re not going to discover some result in the future that’ll make quantum mechanics—or general relativity, or any other well-established physical theory—throw up its hands and disappear.
If we discover that QM is true, we will give up GR. You can’t have both. Sorry mate. You could have something like GR, perhaps, but it wouldn’t be GR.
We very likely will discover results that’ll explain reality better than they do, but that reality includes everything they predict within the domains where they’ve been shown to work well. Science is not a race, nor a battle.
If you want to make QM-domain specific, fine. QM is true in whatever domains saying QM is true doesn’t result in a contradiction with GR. That’s nice and ad-hoc, but you can have fun with that. And it’ll render all the arguments from the truth of QM to broader claims about reality utterly moot. So again, fail.
