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 tested QM results, including the weird ones, have to be explainable by the underlying mechanics.
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. 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.
