I'm sorry if it sounded like I'm dismissing it. Async/await is very useful for massive IO in many programming languages. I've personally worked with a lot of async Python, which can be painful to write. Rust's static typing does make things much better. However, the reason I like Go's approach so much is because it abstracts away all the mundane details about scheduling, and lets us focus on what we want. If we want 1000 threads of execution running concurrently and doing something complex, we can just `go` 1000 functions and pass the corresponding channels to them - the optimal way (MxN coroutine-thread mapping) is already invented and it's been implemented inside the language. Rust will probably always win when it comes to extreme optimizations. Golang's strength is in simplicity and straightforwardness in writing everyday concurrent code.
