A very promising library, although experimental. Even has Android-specific extensions (https://github.com/Kotlin/anko/wiki/Anko-Coroutines).

Of course they have, it is maintained by JetBrains :D

What do you guys think about how it compares to Rx? There are opinions about they are on a different abstraction level so they don't compete with each other.

I agree, coroutines is good for the simpler use cases, while Rx is better for composed transformations. Not sure about using coroutines in prod though, while still experimental.

I’d definitely would wait for the non-experimental release, just in case.
