So why bother using Kotlin?
Seems like it fixes trivial things (makes simple classes a bit more terse) but retains the more fundamental problems and hangs on for Java to actually fix those.

Also, Kotlin usually forges ahead on features, and the Java is playing catch up. Take data classes for instance. If anything it seems like Kotlin gave Java a good kick in the pants to get it to start developing faster and adding modern language features.
If Kotlin is so much better, why doesn't JetBrains just port everything into Kotlin/Native?
Kotlin syntax makes writing functional code beautiful and simple... map and fold and filter are so much easier to write than in any other language that also have the same functions, such as JS. Again, that alone would be enough to migrate.
But there are still so many more simple, but incredibly useful functions like SubstringAfterLast which takes a nasty, ugly Split function into a beautiful, precise line of code. Just one example of many.
Instead, they focus on things like value types. Which are definitely cool, but they don't actually solve any of my problems. Typical business apps written in Java don't suffer from performance issues, they suffer from (accidental) complexity explosion and subsequent buginess (of which NPEs is a symptom).
