I don’t know why but your assumption that others are skating by with what they know rubbed me the wrong way (maybe because I have been on other side of this). There are likely many other valid reasons here - project deadlines (sometimes it is not the right time to pick a new language), consistency of code (having a mix of languages is going to raise hell in code reviews with opinions on some code that could be done better in one language vs other), hiring (does your hiring/onboarding get more complex?), writing idiomatic code (learning a new programming language is easy but writing good code is hard), extreme swing in brevity (people abusing new languages to write concise code using obscure language features, which makes it hard for someone new to jump in).

I am sorry I don’t have any suggestions to fix your problem but I just wanted to provide a bit of perspective. Maybe try thinking from your peers perspective to see what benefits adopting this new language would give and be prepared to answer why Kotlin among a whole class of JVM languages - Scala, Kotlin, Groovy, Clojure.

It’s a very small company and I’m the lead developer. I know exactly what is being worked on and what timelines are involved. The replies I got when I suggested all of this was something akin to “Why now and not before? Why this project and not the others?” Even though the majority of what we work on was originally developed prior to Kotlin going 1.0 and I had already laid out my reasoning. It felt like excuses due to simply not wanting to learn and maintain something new simply because they didn’t see any benefit, even though I also explained the benefits in my original suggestion.

Thanks for your thoughts, though, I’ll take them into account.
