you can use coroutines on the native platform, no?

Yes you can. Of course native is not yet stable so you may hit limitations. But it is a cross-platform system.

So I might not have to bother with threads and such at all

Coroutines on native are currently only single-threaded, so you’re somewhat limited with what you can do.

Oh, I see

There are, but it’s not so easy https://github.com/Kotlin/kotlinx.coroutines/issues/462
