@mr64bit @dcc @nyanide By low-level I mean things like kernels, bootloaders, base system libraries and such. Systems programming is probably a better word for that.

It's fine for writing userspace applications, not so much for libraries that other non-Rust programs would like to use (the equivalent of glibc and similar). That makes it essentially almost useless everywhere but at the end of the whole software chain. Nothing but Rust code can interact with it without breaking easily.
