I think Kotlin is slowly eclipsing Java on the JVM. Its not majority yet but most new projects or major refactors I've seen are either 100% Kotlin or majority Kotlin.
I would not be surprised if Kotlin takes a majority share eventually
Kotlin is Java with minor syntax changes - it brings nothing new to the table and you write it the exact same way as you would Java. It's an easy sell for shops that want the feeling they're making forward progress in the field of computing but who don't actually want to change anything.
That’s factually wrong. Null-safety alone changes completely how you write Kotlin, add to that coroutines, extension functions and dozen other quality of life improvements and you get completely different style.
