Taste Of Your Own Medicine

The classic developer dismissal cycle in its natural habitat. First dev smugly declares "sounds like a skill issue tbh" - the universal code for "your problem is you, not the code." Two weeks later, karma strikes when they hit the exact same wall and suddenly it's "wait no it doesn't work for me either." Nothing humbles a programmer faster than having to eat their own snarky comments when facing the same bug they previously mocked. The circle of dev life is complete.
