This is the ultimate HN circlejerk comment

>Scala, Haskell, Clojure, Erlang (or Elixir) or Go. And there's also the less popular ones like Haxe and Dart

Are you kidding me? Did you just list the languages you see threads on HN about? Scala and Go I could maybe understand if you needed the performance but the rest of the choices are just bad. Especially if you are trying to start a business instead of a functional programming bootcamp.

Also there is nothing inherently more difficult about deploying and distributing python compared to any of the languages you chose.
