Need code fast and free? AI delivers in a flash. Too bad the real bill arrives much later.
In 30 seconds
01AI generates code quickly, but it's often low quality and hard to maintain.
02One developer found half his AI-generated codebase caused huge maintenance costs.

What this means for you
Even if you don't write code, the lesson is clear: free isn't always free when it comes to AI. It's a tool to assist, not replace, human critical thinking.
Tired of AI code that looks like it was written by a drunk sloth? Finally, someone figured out how to leash it, turning "vibe coding" into something serious.

03The hidden cost of AI is the extra time spent fixing "free" code.
When AI promised zero-cost code, many developers breathed a sigh of relief. Imagine: half your work done automatically, without lifting a finger. It sounded like the ultimate solution for impossible deadlines, didn't it?
For one developer, it turned out to be a promissory note that came back with interest. Debashish Ghosal shared his experience on dev.to, where half his codebase was AI-generated. At first, everything was rosy, productivity soared. The code was there, functional, ready to integrate. The temptation to just leave it untouched was strong; after all, it was "free" and "fast."

What's the real cost of "free"?
The problem surfaced by month three, when the AI-generated code began to reveal its true nature. It wasn't elegant, often redundant, and lacked the clarity only a human with an overarching vision can provide. Fixing a bug or adding a new feature became a nightmare, taking much longer than anticipated.

By the third month, 50% of the AI-written codebase required significant maintenance intervention. This means the time saved upfront was repaid with interest in debugging and refactoring hours. AI excels at boilerplate or isolated functions but often misses the project's broader context. Who knew soulless code could cause such headaches?

How do you avoid getting burned?
The lesson is clear: AI is an excellent assistant, not an autonomous programmer. Think of it as a very enthusiastic but inexperienced junior dev. It gives you a first draft, but it's up to you to correct, refine, and intelligently integrate it. Copy-pasting isn't enough; a critical eye is essential.
Experts suggest using AI for initial drafts or repetitive tasks, not for critical logic. This allows leveraging AI's speed without inheriting its flaws. Generated code must always be reviewed, tested, and, if necessary, rewritten. Otherwise, that initial "free" will turn into a very expensive bill.
