I thankfully have not had to use Java for years, but at one of my first jobs after grad school I was hired because I had Kotlin experience and they were moving the code base away from Java.

A few of the older developers also complained about the use of map, filter, zip, lambdas, etc being harder to read as well. Then a month or two later when they realized they weren't going away, it was an important part of the language, and just learned how to use them the complaints just one day stopped.

Except for when we had to touch Java code and it didn't make sense to convert it fully to Kotlin.
