The introduction of quantum mechanical methods for solving physics problems is probably the worst thing that ever happened in the history of the mathematical sciences.
It has brought fundamental progress to a practical halt for an entire century, with no end in sight. It is now also visibly hindering the progress of technologies.
The content-free nature of math means ANY physics problem can be solved by ANY means. So QM ‘finality’ and ‘spookiness’ are superstitions, not science.
