At one point Scala was going to take over the world. It was hot favorite of many fastest growing companies. Then the companies grew and moved to Java with or without much fuss. Your secret does seem like secret to lot of people. In my knowledge Java is big because lots and lots of companies use Java stack for boring enterprise applications. And in those places people could care less about cool stuff and work on things that pays. Cobol is still used in very critical software at big Banks. Java along with it quite respectful place. Whereas Kotlin is a little bit of lot of things. Runs of JS/JVM/Native but none of them a unique strength for Kotlin. So it will be very difficult to compete with languages which committed to single platform and have serious business use cases.
