Kind of. Rust seems to be becoming quite popular. It has features that allow low-level programming while maintaining as much type safety as possible. There's even talk of using it in the Linux kernel.
EDIT: I'm not sure why you ask that here though. Rust doesn't appear to be mentioned in this post.
> I write our firmware using C. While some might gasp at using such an "old" language, it turns out that the combination of my familiarity with C, the maturity of its resources and tooling, and the low-level nature of writing firmware means that C happens to be a joyful language for me to write firmware in.
Which has the flavor of defending the choice of C as if it weren't the standard choice.
Realistically for most micro controllers it's the only choice other than machine code. Basically because it's the only one offered by the manufacturers.
