It's a fantastic language. It combines the conciseness and readability (if you stick to sensible method names) of Python with the safety of OCaml and the performance of Java. It combines the type-level power of Haskell (i.e. the ability to explicitly sequence effects) with traditional OO inheritance/subtyping and performance behaviour you can reason about (helped by the JVM's well-established profiling/instrumentation support). If you want to use a single language for everything, it can scale up to critical core codebases and down to throwaway scripts / interactive notebook-type use. What else would you use?

Oh, no, I was asking mostly as a noob. I've since decided to have a go at learning Scala, and your answer reinforces that decision.
