I'm not convinced that "no inheritance" is better -- drivers seem to be one place where it's actually put to good use -- but I also don't think it really matter

I'm not convinced that "no inheritance" is better -- drivers seem to be one place where it's actually put to good use -- but I also don't think it really matters that much. In contrast, Rust definitely has fewer foot-guns, and that matters a lot. Of course, the OSX driver code is going on 25 years old, so it's not evidence of anyone's opinion that C++ beats Rust for OS dev.
