It refers to async in Rust, and everyone else is responding as if it is talking about async in Rust. That's a mischaracterization. You don't have to use the Tokio executor.

It's a bit like saying, "Graphics in Rust are ruined. I need to use Vulkan to make my game."

No, you don't. If your use case is unique enough, use something else. There are bindings for OpenGL, DirectX, etc.
