Writing an operating system is hard and laborious. There are many bugs beyond memory and there are already many tools the Linux team uses to make it safer. That you can make a better, more stable version of the Linux kernel with rust is still to be proven. Not arguing that the language is not better than C or that, if Linux was being started today, it wouldn't be a more sensible pick. But the language is just one component among many others that make such a projects successful. I would actually be very surprised if there was anything nearly as good as Linux written in rust already. I'm not sure why a company would invest the huge amount of resources to get it done by now and, unless the language had some really unprecedented productivity, I don't think a community led protect would've had it finished by now.
