> Dynamically typed languages like Ruby create a huge surface area for type slop for LLMs, and why I would not recommend using a dynamically typed language for vibe coding.

I totally understand this, and have seen the problems firsthand. But Elixir / Phoenix / LiveView, along with Tidewave, have become my favorite "vibe slop stack." Just so quick and easy, and the LLM seems to get things right quite often.
