Major props for all the work the Elixir team & related technologists have done. Lots of cool stuff there. But it does them I think a disservice to put this as yet another tired Rails vs X argument. Ruby on Rails is not going anywhere anytime soon, including for greenfield app development. In fact, I see Ruby and Rails both picking up some of the cool new features of the Elixer/Pheonix/etc. over the next couple years. So we’ll have healthy competition for a while yet…which is really better for everybody in the long run.
