Just for the record:
More than one year later, I have just observed that Elixir is not in the " The Next 50 Programming Languages" of the “TIOBE Index for August 2018” https://www.tiobe.com/tiobe-index/
It was in that list a month ago https://web.archive.org/web/20180730031822/https://www.tiobe.com/tiobe-index/
and many months before.
