The best way to make that wish come true is to use Rust in a project where you would normally use C, and report your experience to help us discover the best ways to support that use case. :)
I think what personally got me excited about this direction were the many "OS kernel in rust" hobby projects [1, 2]. For some reason these strike me as a sort of reverse canary-in-a-coal-mine to judge whether a language is seen as a potential C replacement.
Prior to rust the hobby OS dev community was primarily C / asm with some honorable mentions for other languages. It's also something of a stand-in for the requirements of the professional embedded community.
For these use cases, it's just really cool to be able to use more and more "layers" of the language as you implement more of the underlying abstract machine model.
