As someone who has written multiple productions services with Async Rust, that are under constant load, I disagree. I've had team members who have only written in C, pick up and start building very comprehensive and performant services in Rust in a matter of days.
How do you developers spew such strong opinions without taking a moment to think about what you're about to say. Rust cannot be directly compared to C#, Java or even Go.
You don't get a runtime or a GC with rust. The developer experience is excellent, you get a lot of control over everything you're building with it. Yes it's not as magical as languages and runtimes like you've mentioned, but the fact that I can at anytime rip those abstractions off and make my service extremely lightweight and performant is not something those languages will allow you to do.
And this is coming from someone who's written non blocking services before Async rust was a thing with just MIO.
The very fact Rust gets mentioned between these languages should be a tribute to the efforts of it's maintainers and core team. The amount of tooling and features they've added into the language gives developers of every realm liberty to try and build what they want.
Honestly, you can hold whatever opinion you want on any language but your comparison really doesn't make sense.
