I find utility is most beautiful. Various other interpretations of aesthetics in mathematics seem misplaced if the result is that none or a very limited number of verifiably consistent applications exist for some new construct/extension of math that is supposedly art but more or less a useless exercise of mental masturbation. Higher theoretical math is purely a construct of reasoning, and may not always produce verifiable consistency for every domain—like reflecting the real (this) universe being studied. I would prefer mathematicians study what is utilitarian and foundational, instead of yet another questionably useful offshoot of mathematics. There are a million dead ends and very few interest pieces that lead to a goldmine of new applications or improvements.
