It may yet be possible to prove mathematically that they are.
It is only one edge case that seems to still be a problem.

In general I agree that at some stage the next level theory will come 
along with some new mathematics where everything that we know at present 
can be derived as a weaker field limiting case.

However, at the moment the contenders like string theory look very 
cumbersome to use even if they actually worked!
