I guess in math they found it just gets more complex, as you go deeper? eventually you need new tools, upon new tools? Is this like philosophy? you just find you need more tools? I'm no expert. And that's why I'm putting question marks around.
At this point I'm fairly sure going deeper (or higher) in mathematics is a dead end, you should instead try to go sideways, to the 'ground level' questions that aren't answered yet, or to the questions that aren't yet mathematical.
I was likely butchering the Godel incompleteness theorem.
