Immutability is its own reward :) Yes yes, available in other langs, but it kinda takes YAGNI in terms of scale off the table since it's a perfectly good fit for small applications as well. It just happens to scale (in terms of concurrency) really well. But if you never need to use those features that's ok—you'll still have an application written in a really nice, expressively terse language.
