I feel like we see the same things with languages as we had with version control. For a long time, you had only CVS, then you had (too) many options to choose from: monotone, darcs, mercurial, git, and I certainly forgot some.

Now, we see new languages appear (and get some exposure) at a frightening pace: Rust, Go for system programming, and on the JVM: XTend, Ceylon, Kotlin, Clojure, Scala, Groovy, etc

It's great to see things move, but when you have so many option, it can be hard to make a choice. I expect some of these to take the lead, like git seems to be doing in the DVCS space.
