I like Kotlin coroutines and I've used them, but they (this argument is controversial) have a function colouring problem. As the JVM adds virtual threads I expect that a rebasing of Kotlin's coroutines will remove that objection.

Plus, sometimes, I want to use Java.

Also debugging with them can be quite painful. It is getting better, but I still pull my hair frequently.
