The Illusion of Code: Why "Vibe Coding" Won't Replace Architecture

Today, every other person feels like a great architect of digital worlds. Just open Cursor or Claude, jot down a couple of lines in plain human language, and voilà: the code writes itself. The phenomenon has been dubbed vibe coding. It seems the barrier to entering the industry has dropped to zero, and any idea can now be built in an evening in front of a TV series. Reality, however, has an unpleasant habit of rapping the knuckles of those who confuse knowing which buttons to press with understanding how the gears under the hood work. The story of an acquaintance of mine, who decided to "quickly" clone a successful Telegram bot, is a perfect illustration of this misconception.

It all started with the classic "how hard can it be?" My friend saw a working service that makes money for its creators and decided that a neural network could assemble an identical copy in a couple of hours. He went into an AI chat, described the functionality and got the first batch of code. At first glance, everything worked. The bot replied, the buttons responded, and he was already picturing passive income. But as soon as the bot met real operating conditions, the house of cards began to crumble. The code written "by vibe" turned out to be completely unprepared for reality, where users behave unpredictably and servers sometimes go down.

The problem with vibe coding is that the AI produces a result that looks right but isn't always right in the long run. Ask it to write a function and it does brilliantly. Ask it to build a complex system and it starts hallucinating about architecture. My friend found that his bot couldn't handle user states correctly, got tangled in message queues and froze dead when it tried to process more than ten requests at once. The AI faithfully wrote code from his prompts, but it couldn't tell him that he had forgotten about database indexes or had configured asynchronous handling incorrectly.

Many beginners forget that modern software is not just a nice interface and basic logic. It also means exception handling, logging, scalability and security. Vibe coders usually ignore these "boring" aspects and concentrate on visible features. The result is a project that cannot be maintained. Any attempt to change code generated by a neural network without a clear plan becomes hell. One fix breaks three other functions, because the system has no coherent structure. This is technical debt, and it accumulates not over years but over minutes.

It's important to understand that AI is a powerful lever, but a lever still needs a fulcrum. That fulcrum is fundamental engineering knowledge. An experienced developer uses a neural network to speed up routine work, but always sees the big picture and knows where Claude may go wrong. A vibe coder relies entirely on "magic" and becomes a hostage to their own prompts. If you don't understand how data flows from client to server and back, no Claude 3.5 Sonnet will build a quality product for you. It will only create the appearance of work, which falls apart at the first serious stress test.

In the end, the bot story ended predictably. After spending a week trying to "tune up" the code through chat, my friend simply gave up. It turned out that the service he was trying to copy had been developed by a professional team not in two evenings but over several months. And the main work there wasn't writing code but designing a fault-tolerant system. Vibe coding is good for building prototypes or testing hypotheses, but it is dangerous when passed off as full-fledged development. Without understanding the basics, you aren't building a project, just playing at imitation.

The bottom line: neural networks are an accelerator, not a replacement for your brain. If you don't know how to build a system by hand, you won't be able to build it with AI either, at least not one that works for longer than a day.
