Off-topic with respect to Kotlin but relevant to the Java platform:

From your perspective, what are Clojure's prospects for contemporary and future alignment with the JVM?

After all, Rich Hickey built the core in 2006-07. Looking at his graph[0] of code introduction and retention in his HOPL-IV paper[1] might imply that either he's that good at the core abstractions or possibly the language could suffer a similar set of limitations as commented about Kotlin above.

I think Clojure has a very different design philosophy and very different goals. Specifically, its abstractions do add overhead -- be it due to immutability or lack of typing -- and that's perfectly in line with its goals. As such, it flies higher above the Java platform than the Java language or Kotlin, and is less sensitive to changes in the underlying platform, as it doesn't try to always closely reflect its capabilities.
