150,000 Lines of Vibe Coded Elixir: The Good, The Bad, and The Ugly

Summary

The author shares their experience using AI to write code for BoothIQ, highlighting the benefits and drawbacks. AI excels with Elixir due to its simplicity and conciseness, but struggles with architecture, debugging concurrent issues, and understanding transaction isolation.

Key Takeaways

1. AI is effective at Elixir coding, especially as the codebase grows, due to the language's small size and terse syntax.
2. AI tends to default to defensive, imperative coding styles and struggles with architectural decisions, requiring human oversight.
3. AI faces challenges in debugging concurrent test failures and understanding transaction isolation, necessitating human intervention.
