Andrew Ng Vibe Coding: What The AI Expert Really Thinks

Have you, perhaps, heard the phrase "vibe coding" floating around the tech world lately? It sounds rather relaxed, doesn't it? A casual approach to building things with code, maybe just going with the flow. Yet, for a prominent voice in artificial intelligence, Andrew Ng, this term actually brings up some strong feelings. He believes the name itself is, well, a bit unfortunate, and it can quite easily mislead people about what's truly involved.

It's interesting how words can shape our perceptions, isn't it? What some might consider a chill, low-effort way to create, Andrew Ng, the Stanford professor and former Google Brain scientist, sees very differently. He has, in fact, spoken out against what he perceives as a troubling trend connected to this idea. He feels the casual name hides a much deeper truth about working with code, especially when you bring AI into the mix.

But here's a twist: despite his reservations about the name, Andrew Ng isn't dismissing the underlying concept entirely. As a matter of fact, he has even launched a "vibe coding 101" short course. This course is specifically for newcomers who want to learn how to use generative AI tools for coding. So, what exactly does he mean by "unfortunate," and how can something he finds problematic also be something he teaches?

The "Vibe Coding" Concept: What's the Fuss?

The term "vibe coding" itself suggests a certain ease, doesn't it? It implies a process where you might just, you know, feel your way through the code, letting intuition guide you. Perhaps it means relying heavily on automated tools, letting them do the heavy lifting while you provide minimal input. This idea has gained some traction, especially with the rise of generative AI tools that can indeed produce code with just a few prompts. It seems to promise a quicker, less demanding path to creating software.

For some, this approach is appealing because it appears to lower the barrier to entry for coding. You don't need to memorize every syntax rule or understand every underlying principle right away. You can, in a way, get something working quickly. This immediate gratification can be quite motivating for people just starting out, and it's something that AI tools are particularly good at enabling. They allow you to see results almost instantly, which is rather exciting.

Why Andrew Ng Calls It "Unfortunate"

Andrew Ng, however, has a different take on the term "vibe coding." He has, in recent discussions, notably at LangChain Interrupt and in an article for Business Insider, called the term "unfortunate" and "misleading." His concern stems from the idea that it suggests a lack of intellectual effort. When people hear "vibe coding," they might assume it's a casual, almost thoughtless activity, which he argues is far from the truth, especially when AI is involved.

He feels that the name misrepresents the true nature of working with AI for coding. It implies that you can just, like, passively generate code without much thought or critical engagement. This, he says, is a dangerous misconception. The reality, according to him, is quite different. It requires active participation and deep thinking, even with powerful AI tools at your side. It's not just about letting the AI do everything; you still need to be very much in charge.

He pushed back against this troubling trend in the world of coding, where the ease of AI might lead people to undervalue the intellectual work still required. The term "vibe coding," in his view, doesn't properly convey the mental effort, the problem-solving, and the debugging that are still very much a part of the process. It's almost as if the name itself is creating a false impression of what coding truly is, even with AI assistance. It tends to suggest a simplicity that isn't really there.

The Intellectual Side of AI-Assisted Coding

According to Andrew Ng, using AI to write code is actually "a deeply intellectual" pursuit. This might sound counterintuitive to some who imagine AI doing all the thinking. But think about it: when you use an AI to generate code, you're not just mindlessly copying and pasting. You need to formulate the right questions, provide clear instructions, and understand the problem you're trying to solve. This requires a lot of brainpower, you know?

You also need to evaluate the AI's output. Is the code correct? Does it meet the requirements? Is it efficient? Does it have any security flaws? This kind of critical assessment is a truly intellectual task. It's about understanding the nuances of the problem and the potential solutions, rather than just mechanically typing lines of code. You are, in some respects, acting like a very skilled editor and architect for the AI's work.

He stated at around 22:30 in a recent talk that "the unfortunately named vibe coding is exhausting if done right." This captures the core of his argument. If you're genuinely using AI effectively for coding, you're not relaxing; you're actively guiding, refining, and debugging. You're thinking about the larger system, how different parts fit together, and how the code will perform. This is a very demanding process, mentally speaking. It's quite a bit more involved than just "vibing."

This approach means you're still doing the heavy lifting of problem definition and solution design. The AI becomes a powerful assistant, but you remain the driver. It's like having a very fast car; you still need to know where you're going and how to steer it safely. The intellectual rigor comes from knowing what to ask, what to look for, and how to fix things when they don't quite work as expected. It's a different kind of effort, but certainly not less effort.

"Vibe Coding 101": A Course for Newcomers

Despite his reservations about the term, Andrew Ng has, as mentioned, launched "vibe coding 101," a short course aimed at teaching beginners how to use generative AI tools for coding. This might seem contradictory, but it actually highlights his practical approach to education. He recognizes that these tools are powerful and that people want to learn how to use them. So, he's providing a structured way to do it, even if he dislikes the popular name for it.

The course likely focuses on teaching the right way to approach AI-assisted coding. It probably emphasizes the critical thinking, the prompt engineering, and the code review skills that are essential for success. For example, in this course, you’ll use Replit’s cloud environment—with an integrated code editor, package manager, and deployment tools—to build and deploy two web applications with the help of an AI. This means you're not just letting the AI run wild; you're using a structured environment to guide its output.

This course is a practical step to ensure that newcomers learn good practices from the start. It's about empowering people to use these new tools effectively, without falling into the trap of thinking it's a passive activity. It's a way to introduce people to the power of generative AI for coding, but with a clear message about the necessary human involvement. You can learn more about AI-assisted development on our site, which can give you a broader view of this topic.

The fact that he created this course shows he's not against the *use* of AI in coding, but rather the *perception* of it. He wants people to understand that it's a tool that requires skill and thought, not just a magic wand. It's almost like he's saying, "Yes, use the tools, but understand what you're really doing." This practical guidance is very much in line with his overall educational philosophy, which often focuses on making complex topics accessible and actionable.

When "Vibe Coding" Makes Sense

Andrew Ng also acknowledges that "vibe coding has its place and it can work." This is a pretty important concession, isn't it? Specifically, he suggests it's useful "when you’re starting out because then there’s very little consequences for poor coding practices and it helps you move a." This means for beginners, getting something working quickly, even if it's not perfect, can be a valuable learning experience. It helps build confidence and momentum.

When you're just beginning, the goal is often to simply see results and understand basic concepts. You're not building mission-critical systems. So, if using AI to "vibe code" helps you get past initial hurdles and reduces frustration, it serves a good purpose. The mistakes you make early on are less costly, which makes it a safe space to experiment and learn. It's a way to get your hands dirty without feeling overwhelmed by the technical details right away.

However, this initial phase is just that: a starting point. As you progress, the need for more rigorous, intellectual engagement grows. The idea is that "vibe coding" can be a stepping stone, not the final destination. It allows you to quickly prototype, experiment, and learn how different components interact. You can, for instance, use it to get a basic structure in place before refining it with more traditional, thoughtful coding practices. This helps you build a mental model of how things work.

So, while the term itself might be misleading, the practice of quickly generating code with AI tools does have a role, particularly in early learning and rapid prototyping. It's a practical application that can accelerate the initial stages of development.
