> Complexity of Scala has been debated many times. Just because a language adds some new concepts and is different than other mainstream languages, is not enough to call it "complex". It seems to me that the JVM community has moved on from Scala and is actively looking for a language that offers most of the benefits that Scala offers without the downsides. Kotlin (from JetBrains) and Ceylon (from RedHat) seem to be the first two languages with a really interesting take on this problem. Gosu and Fantom are similar attempts, although I think these two already failed to gain traction.

To be honest, by the time they are ready for production, Java 8 will provide the most of the features they are promising. So for developers who only want to have lambdas and slightly better libraries (like ability to call filter on a collection), there is no need to move. Just wait for Java 8. On the other hand, for programmers doing some more serious stuff than just moving data from database to the website, they offer too little to be attractive, and they actually haven't solved any problem that Scala hasn't solved (Ceylon's generics reification - a good joke, man). They are nowhere near Scala in expressiveness and flexibility and being only slightly better than Java is not enough for power-coders. There were some languages targeted as "better Java", e.g. Nice long time ago and they also failed. From the alternative languages for JVM, currently only Clojure and Scala (and probably Groovy too) got some serious usage in industry. All others are still in kindergarden.
