For me some of the biggest benefits are:
- Elixir’s syntax is inspired by one of the nicest languages around, Ruby
- Phoenix is inspired by one of the best web frameworks around, Rails
- José and other prominent members of these communities come from Ruby and so it’s very likely that we respect and appreciate similar things. From smart choices to attention to detail, to quality, to little touches here and there, to friendliness in the community.
All that is on top of the fact that Elixir runs on BEAM - making it a battle tested technology and perfect for the modern web.
Some might say Elixir is too good to be true 
and making use of the ‘best’ of everything that’s out there shows that José is a very smart guy
