The duality of programming in one Simpsons meme. Top panel: "Problem solved in under a hundred lines of code" - you're feeling like a coding god, strutting around with pride. Bottom panel: "import numpy as np" - and suddenly you realize your "solution" was just importing a library where someone else already did all the actual work. Let's be honest though - we've all been there. You spend hours trying to write a complex algorithm from scratch, then discover there's a one-liner that does it better. But hey, knowing which library to use is a skill too, right? ...Right?
