GitHub Copilot Limitations: What It Can't Do
GitHub Copilot is ai pair programmer from github/microsoft that suggests code as you type. While it excels at professional developers wanting faster coding, boilerplate reduction, it has significant limitations for building applications from scratch without coding skills. The main issues are: autocomplete, not application building, requires strong developer skills, can suggest insecure or buggy code.
Key Takeaway: GitHub Copilot gets you about 70% of the way to a working app. The last 30% typically requires professional development to achieve production quality.
Main Limitations of GitHub Copilot
Autocomplete, Not Application Building
Copilot suggests code line-by-line. It doesn't build applications or understand high-level architecture.
Requires Strong Developer Skills
Copilot accelerates coding but requires you to know what you're building. It can't replace architectural decisions or debugging skills.
Can Suggest Insecure or Buggy Code
Copilot's suggestions may contain security vulnerabilities, bugs, or outdated patterns. All suggestions need review.
License and IP Concerns
Copilot trained on public code, raising questions about code licensing and intellectual property.

Can GitHub Copilot build me an app?
No. Copilot is an autocomplete tool that suggests code as you type. It doesn't understand what you're building or generate complete applications. You still need to architect and write the application.
Is Copilot worth $10/month?
For professional developers, usually yes. Studies show 30-50% productivity gains. For beginners or non-developers, the value is much lower since you need coding skills to use it effectively.
