Just like Scala by virtue of being a guest language on the JVM ecosystem, never will replace Java on the minds of JVM architects.

Kotlin has an advantage here, because ART nowadays is effectly KVM from Google's point of view, where they grudgingly update Java support to keep up with Maven central.

Scala has nothing like this, and the update on Python alongside native libraries, kind of stole its demand in big data, hence why this kind of scenarios is described on the article.
