I&#x27;m tired of the Kotlin hype (particularly with it unreleased, and so rarely used in production). Many of its features are already part of modern Java, and its language features are very ad-hoc. I can easily see a future for Scala (it offers more radical improvements that Java will never adopt), and maybe see a future for Ceylon (it&#x27;s a very clean design and the union types are a genuine innovation). I can&#x27;t see one for Kotlin.
