Function vs System: The Mindset Behind Code Decay

We’re assigning this function to the new dev… Now imagine this dev is a vibe coder with zero experience 🤣 At first glance, the task looks simple: => prompt => fix But pause for a second. This function is supposed to do one thing. Just one. But does it actually look like it does one thing? Now the real question: Does the dev even know it’s supposed to? The team expects questions, sure… But are those questions meant to fix the issue — or resolve the tech debt? Because if it’s just to fix the issue… The same function gets passed to the next dev. And the next. And the next. Until it finally lands on the lead desk. At that point, it’s no longer a function. It’s a system disguised as a function. Thousands of lines. Handling validation, business logic, logging, error handling… everything. No separation of concerns. No clear ownership. Just patches on top of patches. And tomorrow? You’re back in the same function — trying to understand it all over again. The Pragmatic Programmer said it best: “When you see a building with broken windows, it becomes easier to break the next one.” That’s exactly how codebases decay. The real problem isn’t the function. It’s the mindset. => Fixing issues is easy => Resolving tech debt is intentional Until teams choose the second, this cycle never ends. #devlife #softwareengineering #backend #tech #programming #api
