Chris McCord directly addresses this in his recent ElixirConf talk. There's a threshold amount of training data needed for LLMs to work well, and Elixir more than clears it. Beyond that threshold, having more data doesn't make a tremendous difference. This means the "frustration gap" for newcomers essentially disappears - people who heard "Elixir is good" can now just ask an LLM to build something and start immediately, easing their way into understanding functional programming paradigms in order to be productive. I use Claude Code daily for Elixir development and it understands the language perfectly. The real strategic advantage is that while other ecosystems scramble to solve agent orchestration problems, Elixir/OTP already solved them decades ago.
