A lot of this stuff isn't strictly necessary for many people. But there is a very distinct change in the quality of your thoughts and approaches to solutions after learning advanced mathematics and the theoretical concepts that inform modern systems and abstractions. For instance, Haskell is far easier to someone with prior experience with discrete structures, category theory, and recursion than to someone coming from a purely object-oriented background. Both will be able to write effective code, but it's no question that the mathematically-inclined individual will write more elegant, more concise, and qualitatively better code than the other.
