There are really neat parts of Elixir. For full stack web dev pretend you are building a lego town. Elixir/Phoenix is more of a set of lego bricks vs. Ruby/Rails is completed foundations of sets you are putting finishing touches on and plugging together. At least that is my experience using it. There also is the human aspect of Elixir or arguably any language/framework comparison and inertia to change. One could argue all the technical merits of one vs. another but at the end of the day, successful business outcomes are not going to change much _because_ of the technology choice. It's hard to get a company that has a lot of Ruby/Rails apps and knowledge to commit to training existing developers on something else with the net result being, its just a different language/framework. When you're building data intensive web applications, Rails will scale. The vast majority of cost with data intensive apps is disk storage which it doesn't really matter what web tech stack you're running.
