A modern programming language that makes developers happier.

If (while pitching Kotlin) you're trying to make the case for nullable types specifically in Android, what are some arguments you can use to do so? Sure, just saying that you don't have to worry about NPEs is great, but I'm trying to frame it in the context of Android.

Best example I've gotten so far is like in fragments when you have a callback but the fragment is in the backstack and a view is null, that can bite a lot of people.
