Well they did demonstrate that in a non trivial system of axioms, there will always be true statements that are unprovable. Do they kinda accepted that they will never be able to find everything. https://en.m.wikipedia.org/wiki/Gödel's_incompleteness_theorems
As someone who spontaneously decided to study history / political science instead of physics, although I have been preparing to be a physicist the entire time, I can proudly say: At least I am happy. I spend most of my time doing fun and fulfilling things, instead of showing up at uni at 8 in the morning and arriving home at 8 in the evening just to work on homework. All my friends went into mint and they are stressed, don't have time to do anything and just seem the worst i have ever seen them.
