My experience as well. I was a Perl then Python/R evangelist. But I doscovered and have been using Kotlin (JVM) extensively and TypeScript to a lesser extent for the last 2 or 3 years. And the more I dog and learn about the JVM the less I want to go back. I'm also interested in getting back to Haskell, Scala and Rust I toyed with just to keep my mind open.
