There are a lot of layers of mathematics, the deeper you get, the more difficult it becomes. But for normal applications (like antenna design, machine learning, electromagnetism, cryptography etc), you don't need to get to the deepest level, which are mostly proofs for a formulation of the whole mathematics framework.
Bertrand Russell already pointed this problem 90 years ago(http://www.gutenberg.org/ebooks/13940), but the problem still remains till now.
People now have much higher living condition the people in the past (say 18 century), but you really can't tell if you are happier than them.
