Yeah; I'm pretty sure parts of firefox have already been rewritten in rust. And there's a project at google to start adding rust to chromium too[1].

The linux kernel is adding rust support as a first class language. In time I wouldn't be surprised if large parts of the linux kernel were written in rust. Obviously linux will always have a lot of unsafe code, but unsafe is part of rust too. Its surprising how infrequently you need it.
