Scala was fun when my company was small.

Later, we need to recruit more people, it became harder and harder. Each need to learn a lot before they can contribute bug fix to product. They need to learn:

  - Scala

  - Akka

  - very basic of sbt (if they need to change more than basic usage, they come to me for that change, as I'm the only one who learned complex sbt syntax in our team currently)

  - Play framework

  - Slick

But now, several years later, Akka's license change really make us to consider switch back to plain Java and Maven one part by another. For the actor model, I really like it, it can simplify Synchronization A lot, we researched Vert.X, which seems can do most of Akka (Although I haven't research whether Akka Clustering, persistent can work similar in Vert.X yet).
