Elixir was a wrapper for people who already knew Ruby.
Which is why most Elixir users come to it from the Ruby/Rails community.
It was created by Jose Valim, a Rubyist and Rails committer, who was looking to improve Ruby/Rails concurrency story [0]:
Back in 2010, I was working on improving Rails performance when working with multi-core systems, as our machines and production systems are shipping with more and more cores. However, the whole experience was quite frustrating as Ruby does not provide the proper tool for solving concurrency problems. That’s when I started to look at other technologies and I eventually fell in love with the Erlang Virtual Machine.
I started using Erlang more and more and, with experience, I noticed that I was missing some constructs available in many other languages, including functional ones. That’s when I decided to create Elixir, as an attempt to bring different constructs and excellent tooling on top of the Erlang VM.

People start comparing different languages in different areas and use cases and instead of discussing about the main subject, keep saying oh no my language is more popular or that language is written in C so C is the best...
