In the Age of AI and Vibe Coding, Fundamentals Matter More Than Ever

We’re living in a time where AI can generate code with just a prompt. The rise of tools like GitHub Copilot, ChatGPT, and others has introduced a fascinating new way of writing software—“vibe coding.”

Vibe coding is the art of writing software guided more by intuition, code completions, and AI-generated suggestions than by deliberate architectural decisions or deep understanding of the system. It’s about “going with the flow”—letting the AI fill in the blanks while you steer the direction.

This new style is enabling developers to:

  • Prototype applications quickly without deep knowledge of syntax or frameworks

  • Explore unfamiliar languages and libraries on the fly

  • Generate working demos in minutes

  • Learn through interaction, rather than documentation

It’s changing how we write software. But it’s also raising new expectations.

At its best, vibe coding makes you feel productive. It helps you:

  • Break out of blank-page paralysis

  • Avoid boilerplate and syntax errors

  • Iterate faster

  • Explore possibilities without friction

And in many scenarios—like prototyping or side projects—it works beautifully.

But what happens when you try to take that code to production?

Over the weekend, I tried to set up a TLS connection over TCP using SChannel APIs in Windows with C++. It was my first time manually upgrading a raw TCP socket to a secure TLS channel. In the past, I had always relied on frameworks or configurations that abstracted this complexity away.

This time, I thought—why not vibe code my way through it with AI?

So I did.

I spent hours letting the AI guide me—structuring the code, handling certificates, and attempting the handshake. But after a while, I noticed a pattern: the AI kept repeating the same steps, suggesting the same APIs, just with slight variations. It was stuck in a loop—hoping that doing the same thing differently would eventually work.

It didn’t.

The TLS handshake kept failing. I was probably 80% there—but the last 20%? That required domain expertise, deeper knowledge of how SChannel works, and an understanding of the nuances of certificate handling and security context setup.

That’s when it hit me: AI can accelerate your journey—but it can’t replace the fundamentals.

While AI is making massive strides, production code demands more than just compiling and running.

It requires:

  • Correctness across all edge cases

  • Readability for team collaboration

  • Maintainability over time

  • Performance under load

  • Resilience against failures

  • Security against real-world threats

  • Testability with reliable outcomes

Vibe coding doesn’t teach these principles. In fact, it can hide complexity behind quick fixes—making it easy to skip the learning needed to build scalable systems.

AI won’t replace developers who understand software deeply. It will amplify them.

The developers who thrive in this new era will:

  • Ask better questions to AI

  • Validate and refine AI-generated code with confidence

  • Spot subtle bugs or inefficiencies

  • Know when to trust the AI—and when not to

  • Design systems that are robust, secure, and elegant

To get there, you must invest in the fundamentals. There are no shortcuts.

Here are a few books that have shaped how I think about code:

Most of what I know has come from books—not from AI prompts.

If you've come across great video tutorials, blog series, or courses that helped you strengthen your fundamentals—please drop them in the comments! I’m always looking to learn more, and I’d love to share those resources with others too.

Let’s not just vibe with code. Let’s build with understanding.
