> Some time ago people complained that Scala had only one compiler ... so now they complain about the opposite?
I suspect the "they" that are complaining now about multiple compilers are mostly not the same people that were complaining about one compiler previously.
Elixir as a language may or may not last. I'm betting it will, but even if it doesn't, it works well with Erlang which is going nowhere.
There's more a case against Clojure, granted. I think because Scala is seen as a bridge language is the another reason why it won't last.
