> One thing I find a bit disappointing is the focus on language features. Most of the effort in Java goes into the VM and libraries, while keeping the language conservative. This is because VM/library features have a much bigger impact on application quality, and more directly impact the application's users; moreover, it's a strategy that's proven quite successful. I think people have taken note of the success of Kotlin, and decided that judiciously chosen language features will help user retention/adoption.
