The Problem with Vibe Coding: Why You Still Need to Learn How to Code

As artificial intelligence becomes increasingly capable of writing full-blown applications, and tools like ChatGPT or GitHub Copilot allow anyone to spin up code in minutes, it’s easy to think that traditional software development is becoming obsolete. This has given rise to a growing culture of “vibe coding,” where people dive into projects relying on AI or intuition without deep technical understanding. While this might seem harmless or even exciting at first, the dangers of relying on vibe coding alone cannot be overstated. Here’s why learning to code properly still matters.

1. Security Isn’t Just a Vibe

Imagine you build a weather app with AI’s help. It works fine, and you’re proud of it. But you’ve just pasted an API key directly into your frontend code without knowing you should have masked it. A software developer would know that exposing keys in frontend code is like leaving your house key under the doormat, inviting hackers to steal it and misuse it.

Software developers are trained to write secure code, understanding principles like token expiration, API rate limiting, HTTPS, user authentication, encryption, and input sanitization. These practices don’t show up magically unless you know to implement them. Vibe coders, on the other hand, might build a great-looking app that’s a security nightmare underneath.

2. Privacy: A Legal and Ethical Obligation

With data becoming the new oil, mishandling user information can lead to massive consequences not just for users, but for the developer as well. General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and other data protection laws have strict rules about how user data must be stored and processed.

Trained developers are familiar with data privacy standards, how to anonymize data, where to store it securely, and how to handle user consent. A vibe coder might not even realize they’re violating a law by collecting location data without disclosure or by storing passwords in plain text.

3. Front-End vs. Back-End: It’s Not All the Same

One common issue among vibe coders is the confusion between front-end and back-end. They may build something that looks amazing on the screen, but when it comes to database logic, server performance, or RESTful API design, things fall apart.

Building modern, scalable applications often requires deep understanding of both layers and how they interact. Some apps even go further, incorporating an entirely separate back office system to manage user data, settings, or analytics. For instance, in one real-world example, an app might use:

Laravel for the back end (PHP framework)
Flutter for the mobile front end (cross-platform UI)
Angular for the admin dashboard or back office (TypeScript-based SPA framework)

This kind of modular architecture isn’t just plug-and-play. It demands experience, planning, and a grasp of different tools for different purposes.

4. Knowing the Right Tool for the Right Job

A key sign of a skilled developer is knowing when to use a specific framework, language, or approach. Should you use GraphQL or REST? Should you deploy to AWS, Firebase, or a VPS? Should you build a native app or go with a hybrid framework like React Native or Flutter?

Vibe coders often pick whatever feels trendy or appears first in a YouTube tutorial. They may not know the trade-offs, performance issues, scalability concerns, or compatibility headaches. A lack of foundational knowledge can lead to bloated apps, poor user experience, and apps that simply don’t scale.

5. Optimization Isn’t Optional

A working app isn’t necessarily a good app. Without understanding things like:

Lazy loading
Asset compression
State management
Efficient database queries
Memory management

…your app may work today, but crawl tomorrow as your user base grows. Developers with a strong coding background build apps that are optimized, fast, and energy-efficient. Vibe coders often don’t know where to begin when performance starts tanking.

6. Debugging, Refactoring, and Maintenance

Real-world apps break. They evolve. Features change. Bugs show up in edge cases you didn’t think about. Without coding fundamentals, vibe coders are stuck when the AI-generated code stops working. They can’t debug beyond surface level or refactor code to scale with new features.

Knowing how to read a stack trace, trace a bug, refactor code for modularity, and write tests for stability is part of what separates hobbyists from professionals.

7. AI Is a Tool, Not a Replacement

AI is powerful, but it doesn’t understand your app. It generates patterns based on vast training data. If you don’t understand what the AI gives you, you’re not coding. You’re copy-pasting. True developers use AI to augment their work, not to replace their knowledge.

Just like calculators didn’t eliminate the need to understand math, AI won’t eliminate the need to understand code. In fact, the developers who will benefit the most from AI are the ones who already know how to code well.

Final Thoughts

Vibe coding might feel fun, creative, and empowering, and it’s a great way to start exploring programming. But if you’re serious about building reliable, secure, scalable, and maintainable applications, learning to code is still essential.

Whether you’re building a startup, freelancing, or contributing to open-source projects, deep coding knowledge gives you the edge. Not just in building apps, but in building better ones. Don’t just vibe. Learn. And then code with confidence.

TL;DR: Vibe coding may help you get started, but real coding skills will take you further and protect you from costly mistakes. Learn to code, properly.
