Kotlin, Frege, Clojure, Fantom, Ceylon, JRuby, etc. There's a language for everyone. So building more value into the JVM with projects like that would be really great.
The JVM is probably the most advance VM currently, and hopefully it'll just keep getting better, maybe faster startups with the new module system, hopefully in java 9 they add value types, etc. All to say, I think more people should look into the JVM as a platform for the future.
