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

TL;DR:

  • Good: AI is great at Elixir. It gets better as your codebase grows.

  • Bad: It defaults to defensive, imperative code. You need to be strict about what good Elixir looks like.

  • Ugly: It can’t debug concurrent test failures. It doesn’t understand that each test runs in an isolated transaction, or that processes have independent lifecycles. It spirals until you step in.

  • Bottom Line: Even with the drawbacks, the productivity gains are off the charts. I expect it will only get better.
