Why GitHub Copilot is Overrated: 5 Misunderstandings People Have

As a solo founder or indie hacker, you’re always on the lookout for tools that can save you time and enhance your productivity. Enter GitHub Copilot, which many swear by as the ultimate coding assistant. However, after spending considerable time using it, I can confidently say that it’s overrated. Here’s why, along with five common misunderstandings about this AI coding tool.

Misunderstanding #1: It Writes Perfect Code for You

Reality Check: GitHub Copilot can generate code snippets based on context, but it’s not infallible.

In practice, I’ve found that while it can speed up boilerplate code, it often misses edge cases and produces inefficient solutions. You still need to review, refactor, and sometimes entirely rewrite the code it suggests.

Limitations: It’s not a replacement for understanding the fundamentals of coding. If you don’t have a solid grasp of programming, relying on Copilot might lead you to implement poor coding practices.

Misunderstanding #2: It Works Seamlessly with Any Language

Reality Check: While Copilot supports a variety of programming languages, its performance varies significantly.

For instance, it excels in JavaScript and Python but struggles with less commonly used languages like Rust or Haskell. If your project involves niche languages, you may find Copilot less useful.

Limitations: The AI is trained on public code repositories, which means it may not have sufficient context for proprietary or unique programming languages.

Misunderstanding #3: It's Cost-Effective for Everyone

Reality Check: GitHub Copilot costs $10/month or $100/year. For small projects, this can add up quickly, especially if you’re not getting the value you expect.

If you’re a solo founder just starting out, you might find better returns on your investment by spending that money on a quality course or documentation instead.

Limitations: If you’re not using it daily or for every project, the cost may not justify the benefit.

Misunderstanding #4: It Eliminates the Need for Documentation

Reality Check: Some believe that Copilot can replace the need for formal documentation. This couldn't be further from the truth.

In our experience, the code generated by Copilot often lacks context. Documentation is essential for understanding the "why" behind your code, which is something Copilot doesn’t provide.

Limitations: Relying solely on AI-generated suggestions can make it harder for you and your team to understand the overall architecture of your project later on.

Misunderstanding #5: It’s a One-Stop Solution for All Coding Challenges

Reality Check: While Copilot can assist with many coding tasks, it’s not a panacea for all your coding problems.

There are still plenty of scenarios where human intuition and problem-solving skills are irreplaceable. It’s a tool, not a replacement for a developer’s critical thinking and creativity.

Limitations: It can’t understand your project goals or nuances; you still need to guide the development process.

What We Actually Use

In our stack, we primarily rely on Tabnine for its flexibility and effective autocompletion, especially when we’re working on JavaScript projects. For Python, we lean on Sourcery to refine our code. We use ChatGPT for brainstorming and discussing coding strategies, but we don’t rely on it for actual coding tasks.

Conclusion: Start Here

If you’re considering GitHub Copilot, think critically about what you actually need for your projects. While it can be a helpful tool in your coding arsenal, it’s not the silver bullet many make it out to be. Consider exploring alternatives like Tabnine for more effective coding assistance while saving costs.
