150,000 LINES OF VIBE CODED ELIXIR: THE GOOD, THE BAD, AND THE UGLY

Summary from the TLDR Dev newsletter

BoothIQ used AI to write all 150,000 lines of its Elixir codebase, finding the language's small, terse, and immutable nature great for AI generation. AI is great at generating code efficiently, especially when aided by Elixir-specific tools like Tidewave. However, it struggles with architectural decisions, often produces defensive code trained on imperative languages, and is ineffective at debugging complex Elixir concurrency and understanding isolated test environments.
