> If people really want a pure, statically typed language Kotlin is pretty good and has less impedance mismatch with Java.

I see this the other way around: Java genuinely has eaten most of the good parts of Kotlin, because Kotlin is positioned as a small enhancement over Java rather than a language that brings major improvements as Scala does. Adopting Kotlin means paying much the same cost as adopting Scala, but for much less in the way of benefits.

This is why Kotlin is such a hit for Android devs, who are stuck with only half the features of Java 8 (at best).
