I haven't used Kotlin, but glancing over their comparison page the one that jumped out to me was that it (almost) eliminates the possibility of null pointer exceptions: https://kotlinlang.org/docs/reference/null-safety.html

This is my litmus test to determine whether a modern language is not terrible. Why wouldn't you want to eliminate an entire class of errors?

Unfortunately, my day to day language at work is Go.

This is like an entry-level expectation for a modern language. Hardly something to write home about in this day and age.

It is when you bring it first-party to a platform the size of Java.

The userbase of Objective-C was much smaller before OSX brought Cocoa to the Mac ecosystem.
