Inheritance Memes

You spent three days architecting an elaborate class hierarchy with abstract factories, strategy patterns, and enough interfaces to make a Java textbook jealous. You added protected methods, virtual functions, and meticulously documented extension points because "someone might need to extend this someday." Plot twist: You're the only developer on the project. The "someone" who will extend it? Also you. And you never will because YAGNI exists for a reason. The skeleton perfectly captures that eternal wait for validation that your over-engineered masterpiece was worth it. Spoiler alert: three months later you'll refactor it into a single function and wonder what possessed you to create 12 classes for a feature that validates email addresses.

When you make a Car extend Person instead of the other way around, you've created an inheritance hierarchy so cursed that even Barbara Liskov herself would need therapy. The Liskov Substitution Principle states that objects of a superclass should be replaceable with objects of a subclass without breaking the application. But here? A Car IS-A Person? Brother, you've violated not just SOLID principles but the laws of physics and common sense. The person crawling on the ground represents every senior developer who has to review this code. They're not just disappointed—they're physically broken by the sheer wrongness of it all. A car doesn't inherit from a person. A car HAS-A driver. Composition over inheritance, my friend. But no, someone decided that giving a Car a topSpeed and passing a driverName to super() made perfect sense. Fun fact: The Liskov Substitution Principle is the "L" in SOLID, named after Barbara Liskov who won a Turing Award. She definitely didn't win it for making vehicles inherit from humans.

You know that senior dev who insisted on writing production code in Microsoft Word because "it has syntax highlighting if you squint hard enough"? Yeah, their decisions are now your problem. The parallel here is brutal: just like poor lifestyle choices during pregnancy can affect the child decades later, that cowboy coder who merged straight to main without tests in 2004 has cursed you with a codebase that imports time , datetime , AND requests in a file called utils.py that somehow controls the entire authentication system. The YouTube video claiming Word is the "best IDE for programming" is the cherry on top. Some sins echo through eternity, and using Word as an IDE is definitely one of them. The tech debt doesn't just compound—it metastasizes.

Every OOP developer's journey: First you discover inheritance and polymorphism and suddenly you're an architectural genius, creating elegant hierarchies where a ChessPiece extends MovableGameEntity which implements IPositionable . You're writing beautiful recursive algorithms, feeling like a wizard. Then reality hits. You've abstracted so hard that your chess pieces are now just pure data with zero behavior, floating in a sea of interfaces seven layers deep. Your bishop doesn't know how to move anymore—some MovementStrategyFactory three folders away does. You need a PhD and a map to figure out where the actual logic lives. The duality of OOP: powerful enough to model the entire universe, confusing enough to make you question if your knight should even exist as an object or just be a JSON blob processed by a ThingDoer class.

Senior devs roasting juniors with the holy trinity of code review sins. "Where's your base class?" "He duplicated code that could have been abstracted!" "I bet he doesn't even know how generics work!" Meanwhile the junior dev is just standing there taking it from all angles like some kind of OOP intervention. The beautiful irony? Give it 6 months and that same junior will be pointing fingers at the next newbie who dares to copy-paste a function instead of making it reusable. The circle of life in software development—everyone gets hazed by inheritance patterns and DRY principles until they become the hazer. Pro tip: If you're getting roasted for all three simultaneously, you've probably written a 500-line god method that does everything. We've all been there. Some of us still are.

You get assigned to a "new" project, thinking it's a fresh start with clean architecture and modern practices. You open the codebase. You check the deadline: Q3 2025. That's... soon. Very soon. Then you actually look at the code and suddenly understand why the last three developers mysteriously "pursued other opportunities." That wide-eyed stare of existential dread perfectly captures the moment you realize the "new" project is actually a Frankenstein's monster of deprecated dependencies, no tests, commented-out code from 2018, and TODO comments that say "fix this later" with a timestamp that predates the pandemic. The deadline hasn't changed though. Q3 2025. Better start brewing that coffee.
