What I hate about Scala School is that they are still using Twitter Future's and not Scala Future's, that could be aweful for Beginners.

The Scala school course has not been updated for a long time. I am not sure its a good resource anymore.

Twitter's Futures were developed when Scala's Futures weren't tail-recursive (and so not really production-quality). There's probably an item on the roadmap to port Finagle to using scala.concurrent.Future but I doubt it's high priority. The two support the same set of operations in any case - I doubt it'd be a huge problem for a beginner to translate one to the other.

Actually a Huge difference is that scala.util.Future takes a implicit ExecutionContext while com.twitter.Future does not.

It is for production. It's not for a beginner - they should just be using scala.concurrent.ExecutionContext.global.
