Elixir is somewhat lacking in training data compared to some more popular languages, so AI will often regurgitate nonsense (more so than in more popular languages).

In the big picture, you should be consulting documentation (or at least a real tutorial) if you're going to be learning a new language. Hell, I'll use AI to bootstrap my knowledge when possible, but it's always important to fall back onto the old method when the quick-and-dirty AI attempt doesn't work out.
