What exactly is vibe coding?

Vibe coding is a development method where AI generates code from natural language prompts alone. You can create apps or web services with just ideas without knowing complex syntax, and it's gaining attention to the point that global VC funds are flowing in.

If AI takes over coding, what should developers do now?

Developers should focus on analyzing requirements and designing system architecture. Instead of writing code directly, they shift to evaluating the quality of AI-generated code and making structural decisions that consider maintainability.

Why are non-coding skills important in product-level software?

Dependency structure management, scalability, security, exception handling, etc. are areas that AI finds difficult to solve automatically. Product-level software must be designed to be maintained over a long period, not just to work, so these non-coding design skills are critical.

What are some pitfalls of vibe coding?

The illusion that coding has become easy can lead to rapid accumulation of technical debt. AI-generated code may appear to work, but internally it can be highly complex or vulnerable to exceptional situations, which can later incur huge refactoring costs.

How can human developers exercise creativity in the AI era?

Human developers critically evaluate AI outputs, plan original features reflecting user needs, and provide overall direction aligned with business goals. Creativity comes from the way of solving problems and envisioning systems, rather than from the code itself.

"Code Was Never the Hard Part" — Where the Real Value of Developers Lies in the Vibe Coding Era

md-logAugust 9, 20264 min read

As AI makes coding easier, non-coding skills like problem definition, system design, and dependency management become crucial. We analyze the changing value of developers and hidden pitfalls amid the vibe coding craze.

Nowadays, the "vibe coding" craze is strong. With just natural language commands, AI writes code for you, so rosy prospects that anyone can build an app are pouring out. But developers in the field shake their heads and say: writing code itself was never that difficult. As AI lowers the syntactic barrier, the real difficulties have become even clearer. Defining what to make and designing how to structure it are things AI can never do for us.

Code Is Just a Means, the Real Challenge Is Problem Definition

Vibe coding tools produce prototypes incredibly fast. But there is a huge gap between coming up with an idea and building a properly working product. Understanding what customers truly want and translating vague requirements into concrete features still requires human insight. For example, a single prompt like "make a shopping mall for me" cannot capture hundreds of decisions. Payment process flow, inventory management integration, user experience design—these are areas where developers must understand the business context and make judgments.

This change fundamentally redefines a developer's value. No longer is it about being a coder proficient in a specific language's grammar, but about becoming an architect who defines problems and establishes solution strategies. As emphasized in the hot YouTube video "Vibe Coding Dependency Lecture 1," to create product-level code, non-coding skills like dependency structure management are critical. To prevent AI-generated code snippets from becoming tightly coupled and turning into an unmaintainable mess later, the insight to design loose coupling and clear interfaces from the start is essential.

Engineering Sense That Shines at the Product Level

Building a toy project as a hobby is completely different from developing a product to launch in the market. While vibe coding can produce results quickly, for that code to survive years of being touched by multiple people, it needs a solid foundation. For instance, even when adding a single API call, the habit of meticulously adding retry logic or exception handling for failures is hard for AI to automatically adopt. According to a report last July, global VC funds are flowing back into vibe coding startups like Lovable, heightening the fever, but funds don't guarantee code quality.

Technical debt accumulates invisibly. Just because AI-generated code works right now doesn't guarantee that the internal logic is efficient or secure. In fact, among early vibe coding startups, there are quite a few cases where they had to undertake massive refactoring after quick launches due to unexpected edge cases and security vulnerabilities. The more we mistakenly think coding has become easy, the more these hidden complexities become bigger pitfalls. Given the nature of software where maintenance costs far exceed initial development costs, code spewed out without solid design from the start will eventually trip you up.

What Only Humans Can Do: Evaluating and Directing

AI is a powerful assistant, but it doesn't always make the right decisions. Humans must judge whether the generated code truly satisfies requirements, has an extensible structure, and fits well with existing systems. Especially creative problem-solving and delicate considerations for user experience remain human territory. The reason content like "Anyone can develop, but numbers only real developers know" gains attention reflects the developer's discernment that has become more urgent in the AI era.

Ultimately, in the vibe coding era, developers evolve from 'code producers' to 'code evaluators and directors.' In this process, tools that transparently record numerous design alternatives and code change histories generated by AI and enable real-time review and collaboration are essential. For example, using a human-in-the-loop archive like md-log allows you to accumulate when and what decisions were made, turning them into the team's knowledge asset. What's more important than the speed of writing code is writing the right code and building sustainable systems. The vibe coding craze is actually making it clearer that human judgment and collaboration are at the center.
