To me, the benefit is what Kotlin has <i>less</i> than Scala.<p>It&#x27;s an incremental improvement over Java and it fixes exactly all the complaints I have over Java and nothing more.<p>Also, its IDE support is just as good as Java.<p>But the language is not even out officially, let&#x27;s see in five years how it fares. Right now, it&#x27;s just a breath of fresh air over Java.
