Because history has proven that multiple times.

UNIX and C, Web and JavaScript, Windows and .NET/C++, macOS and Objective-C/Swift, Android and J̶a̶v̶a̶/Kotlin/C++....

Google only cares to push Kotlin on Android, and it only matters because Google visibly doesn't want to move Java beyond the Java 8 subset that Android currently supports, so the choice is between an handicapped Java support or Kotlin.

Until there is a JVM written in Kotlin, and Kotlin gets first class support in all Java IDEs instead being a tool to sell InteliJ licenses, it is just yet another language that happens to target the JVM.

This ignoring that Kotlin already has a couple of impedance mismatches with the JVM, sequences vs streams, lambdas vs SAM, co-routines vs fibers, inline classes vs data classes.

Elixir is doing well because many developers seem wary to learn Prolog/Erlang syntax.
