There is some current work on interpretations of quantum mechanics. How do you think can interesting results in that area help physics? Can it change quantum physics or make it easier? Which interpretation has to potential to change practical QM calculations? I mean if MWI turns out the best, then so what? It neither provides more intuition nor makes it calculations easier.
If there are axioms and QM is derived from these, is there any practical value from this mathematical approach? I thought a statement like "it's the only mathematically consistent solution to the axioms", would provide no practical value?
How is knowledge about QFT important to interpretations of QM or is QFT merely a handy mathematical framework?
