I wouldn't call it a new language, for me it's just a syntactic sugar over Java, but for any problem you would google "how to do X in Java", not "how to do X in Kotlin".
But there you can do way simpler syntax, like:
0..100 meters with -45..45 deg within 3 seconds
Because "0..100 meters ..." is equivalent to "(0..100).meters(...)"
(0..100) is a built-in IntRange type, that you can extend:
data class MyDistanceRange(val meters: ClosedRange<Double>)
val IntRange.meters: MyDistanceRange
get() = MyDistanceRange(first.toDouble()..last.toDouble())
IMO Kotlin has some features that take it way beyond just being syntactic sugar over Java. Like, I know you could probably use some eye-watering gang-of-four pattern to achieve the same effect as extension methods. But it's going to be such a PITA to maintain that calling the Kotlin feature syntactic sugar for the same thing is about as useful as saying that function definitions are just syntactic sugar over assembly language calling conventions.
I've played with it for a bit but it doesn't excite me enough to spend time learning it properly. I also don't care about Python beyond using it for learning algorithms and maybe some smaller Pyside UIs.
However, together with Mojo it might become more interesting again.
