If we're going to be frank about it, higher level math is:
1) Intellectually challenging, to such a degree that those wishing to enter the field need to have a certain level of intellectual prowess to do so. This creates some levels of mystique, with a sprinkle of elitism and gatekeeping.
2) Driven (among other things) by prestige. And the more pure the math is, the more prestigious it is.
3) So complex that people can spend their entire working careers chasing a handful of problems. The amount of time researchers spend on very specific problems is mind-boggling, if we think about the results.
4) Intensely captivating for the people deep in the weeds.
And the deeper you get, the longer you study, the more you start to value things like "mathematical beauty", and may start to view math as a form of art.
Like many similar fields, you end up with this ivory tower where people can dedicate their whole lives to thinking deeply about extremely niche and theoretical problems.
Similar things are happening in the competitive programming world.
Quite a lot of people are not happy they aren't elite anymore, and many have spent years to decades to arrive here.
Simply put you invest years of your life to establish a kind of distinction over others, and that goes away. That hurts.
But its not something surprising. Most of these competitive programming problems were actually English languages puzzles, because you couldn't dial up the mathematical difficulty anymore making it a fields medal problem. And in most cases in simple language weren't even that hard to begin with, and you could look up solutions to these problems in an hour of Google searching.
