actually I'm still unsure about kotlin. some things are really great some things are not. I mean i will still use kotlin, especially for libraries since it is great for that. however somehow I still missed something on top of Executors and CompletionStage. And I'm totally unhappy about "So, why doesn’t Kotlin have its own package manager, or its own build system? Because there’s already Maven and Gradle, and re-using their huge number of plugins is crucial for many projects." The answer would be totally valid, however people who worked with maven, gradle, ant or even sbt (which isn't offically supported) could be unhappy. all of these build systems are useful, but not actually great. I mean you could work with them but it's not actually great to use them.

You could use RxKotlin. It has Schedulers and Observables/Single/Completable for interacting with async tasks. https://github.com/ReactiveX/RxKotlin

Can you name any criticism of Gradle? I've used it for years now (for Android development). It's steadily being improved, and is really good in my opinion.

Kobalt is a clever and fast build tool written in Kotlin. It is much simpler to use than the others you mention and still works with maven repos

kotlin looks like swift for java. I hope google will remove java and start adding kotlin as a first citizen :)

The trouble between google and oracle wasn't about Java, it was about the Java Standard Library and Harmony. Which wouldn't really be solved by Kotlin.

Actually criticism is mostly personal however there are a few:

    - I dislike the DSL // not a really useful criticism I know.
    - Some things needs Groovy which isn't a mainstream language
    - Had Bad support for Scala, which I use heavily mostly resolved since 2.2 and thanks to linkedin newer version even have twirl + playframework support.
    - sometimes the syntax file of the DSL couldn't be highlighted in eclipse / intellij
    - Bigger build files could be really slow (mostly resolved in newer versions)
Btw. whats really really good on Gradle is the dependency resolution, which is really fast compared to something like sbt.
