The thing is in many cases you had to make a choice between performance and productivity. With
things like Elixir&#x2F;Phoenix you don&#x27;t really have to make that choice. Maturity argument again is moot as you are building on top of Erlang&#x2F;BEAM that&#x27;s very mature and has very good tooling. For people coming from Ruby the syntax also makes transitioning less of a pain.
