I've just started learning Elixir very recently after nearly 23 years of working solely with languages such as VB, C, C#, Ruby, Python, Javascript, and Go.

I know exactly what the presenter means when he says learning a language should be a "mind-blown" event. It's opening my eyes to an entirely new way of thinking about solving challenges. Absolutely love it, and I feel like I did myself a serious disservice for not learning something like Elixir or Erlang earlier in my career as opposed to always learning just another new imperative language.
