Is it really that incredible? Look at how Kotlin implemented coroutines. The language support is tiny - nearly everything is implemented in libraries that you can compete with. In particular the language rejected the async/await model: you still mark functions as async (suspend) but there's no language level equivalent of await. Just lots of library level APIs to compare coroutines in different ways. It's really nice.
