Languages without platforms fade away, history is full of examples.
For better or worse, Kotlin designers have decided to make a deal with Android for turning it into Kotlin's plaform, and they definitely do not care what happens with the JVM.
Kotlin designers will eventually, like everyone else, find out that one cannot stand on both sides when things start heating up.
Then there is the whole matter of ChromeOS vs Android vs Fuchsia of Google's internal politics, and Kotlin is only relevant in one of them.
I also find language politics to be incredibly boring. Maybe you have a point, but I just want to write code in a language that isn’t 10 years out of date.
