Fantastic article. My experience with Rust as an enthusiast was that tutorials tend to introduce Tokio very early on and it kinda makes Rust feel more difficult than it is. Rust's async shouldn't be taught, it should rather be discovered.

The author mentions

> If async is truly indispensable, consider isolating your async code from the rest of your application

I think ALL async code should be generally isolated.

Are there languages that provide foundational priority to asynchronous code yet supports good intermingling of sync and async in the same codebase? I maybe missing the point about isolation, but the mix of sync and async code gets bad really quick.
