In February 2025, Andrej Karpathy gave a name to what many developers had already been doing for months: “vibe coding.” This term describes the increasingly popular approach of expressing code requirements in natural language to AI systems like Claude or ChatGPT, then refining and testing the generated result. While the practice itself isn’t new, having a catchy name has brought this methodology into the spotlight of software development discussions.
What Exactly Is Vibe Coding?
At its core, vibe coding is simple. Instead of writing code from scratch, you describe what you want in plain English to an AI assistant. Want to validate that a country exists in your shipping form? Instead of building a lookup table manually, you might prompt, “Write me a function that validates if a user’s input is a real country.” Within seconds, you get a complete function ready for implementation.
This approach offers an enticing alternative to traditional coding methods, especially for those intimidated by programming syntax or professionals looking to expedite routine tasks. But like any technological shortcut, it comes with both advantages and hidden costs.
The Shift, Not the Elimination, of Work
One common misconception about vibe coding is that it eliminates programming work entirely. The reality is more nuanced – it shifts the nature of the work from writing to explaining and reviewing. However, this shift isn’t always beneficial.
For experienced developers who can type code faster than they can articulate requirements, vibe coding might actually slow them down. The time spent crafting the perfect prompt, waiting for generation, then meticulously reviewing unfamiliar code could exceed the time it would take to simply write the function themselves.
Additionally, natural language is inherently more ambiguous than programming languages. What seems like a clear request to you might be interpreted differently by an AI, leading to code that doesn’t quite match your intentions. Debugging these misunderstandings adds yet another layer to the review process.
Navigating the Unfamiliar Territory of Generated Code
When you vibe code, you’re stepping into uncharted territory with each generation. As Mark Kelly, Founder of AI Ireland observes, “With vibe coding, you’re not just reviewing code – you’re deciphering digital artefacts created through an alien thought process, making you both detective and editor simultaneously.”
This powerful analogy captures the fundamental challenge: interpreting and validating code that emerged from a system that thinks very differently than you do. Unlike human-written code that follows recognisable patterns of logic and problem-solving, AI-generated solutions may take unexpected approaches that require careful examination.
Human attention is a finite resource. Our brains naturally seek patterns and can gloss over details when reviewing large blocks of unfamiliar code. These momentary lapses in attention can allow subtle bugs to persist – bugs that might have been avoided had you written the code yourself with a clear understanding of the logic flow.
Who Benefits Most from Vibe Coding?
For beginners, vibe coding offers an unprecedented opportunity to implement functionality beyond their current skill level. Having a 24/7 tutor providing custom, working code examples lowers the barrier to entry for programming significantly. However, over-reliance on generated code without understanding the fundamentals could hamper long-term skill development.
For experts, vibe coding shines in specific contexts: exploring unfamiliar languages, generating documentation, implementing tedious boilerplate or quickly comparing different approaches to solving a problem. Used selectively, it becomes another tool in their arsenal rather than a complete replacement for traditional coding.
Finding the Balance
The growing popularity of tools like GitHub Co-pilot and Cursor indicates that vibe coding is here to stay. The most effective approach is viewing it as an enhancement to – not replacement for – programming expertise.
True experts are becoming increasingly selective about when and how they use AI coding assistants. They recognise that some tasks benefit from vibe coding’s speed and convenience, while others demand the precision and control that comes from writing code manually.
Looking Ahead
As AI coding assistants continue to improve, the line between vibe coding and traditional programming will likely blur further. A developer who never uses AI assistance may soon become as rare as one who never uses version control or debugging tools – it will simply be another essential skill in the modern developer’s toolkit.
The key for developers at all levels will be developing discernment about when to leverage AI assistance and when to rely on their own expertise. Those who master this balance will gain significant advantages in productivity without sacrificing understanding or control.
Vibe coding isn’t the end of programming as we know it – it’s just the latest evolution in how we translate human intent into machine instructions. Like any tool, its value depends entirely on how we choose to use it.
