So, current status on async

Rust - you need to understand: Futures, Pin, Waker, async runtimes, Send/Sync bounds, async trait objects, etc.

C++20, coroutines.

Go, goroutines.

Java21+, virtual threads

The facts that Send/Sync bounds model are still relevant in all the other languages, the absence of Send/Sync just means it's easier to write subtly incorrect code.
