For all the people downvoting - despite what the clickbaity title might suggest this is not a slop post by some AI evangelist.
This is in fact an article by Elixir creator José Valim, where he comments on a recent study which showed that models had on average much better performance using Elixir to solve problems out of the 20 languages tested.
He makes some solid arguments to explain why that could be the case and why Elixir is particularly easy to work with for LLMs as well as humans.
