This is an interesting observation. Some of the data scientists I work with have been using Kotlin to define "analytic grammars", and is the first example (in my limited Kotlin awareness) i've seen of Kotlin outside of Android development.

It seems that Roman Elizarov (Kotlin Project Lead) has identified the opportunity for a better language ecosystem to enter the data science space
