Elixir is a lot more readable for newbies (especially people with a Ruby background), which is what I assume they mean by "user friendly". Elixir also has some nice libraries as well... one I've been digging into recently is GenStage, which gives you a way to organize process communication sort of like a conveyor belt, except that processes request more work from producers, allowing you to build a system that isn't going to break down as processes get overwhelmed.
