> Already parts of the Linux kernel as well as Windows are being written in Rust, so if it's good enough for them, it should be good enough for those bunch of C experts.

The C experts I was referring to are the subsystem maintainers and none of them are currently working on migrating to Rust AFAIK. So far the work in Linux with Rust has been a few driver rewrites. Keep in mind that there are subsystems like eBPF, io_uring, etc. that are under rapid development and are completely in C. I think if you really believe that kernel code should be written in Rust, you should start submitting patches instead of telling people that they have some sort of moral obligation to use Rust when you aren't the one that has to do any of the work.
