I was looking into Rust a few months ago and noticed that most jobs listed seemed to be Web 3, crypto scams. It doesn't seem to be in high demand, from the corporate side of things.
I expect Rust to be inevitable in embedded development, but yeah, that space moves slow, so give it another ten years or so. I will say that embedded is practically jumping on Rust, compared to how glacially it normally moves. You've got big vendors committing to offering Rust APIs, because many of their customers just don't want to code C/C++ anymore.
