Vibe Coding Gets You 80% Done Fast, But the Remaining 20% Kills Your App

The author points out that while "Vibe Coding" (using natural language prompts for AI to write code) can complete 80% of an application's basic features in an afternoon, the remaining 20% is often what determines a project's success or failure.
These easily overlooked fatal pitfalls include:
- Context drift & agent amnesia: AI easily loses background information during long conversations or complex projects.
- Zero test coverage & silent breaks: Generated code lacks tests, making it highly prone to introducing unnoticed bugs when modified.
- Technical debt at 10x speed: Rapid code generation leads to messy architecture and drastically increases later maintenance costs.
