Greg Kroah-Hartman... urged fellow contributors to embrace those interested in contributing Rust code to improve the kernel.

"Adding another language really shouldn't be a problem... embrace the people offering to join us

In my mind, introducing Rust would only make sense if:

  1. There was a serious lack of current kernel developers (which I don't think there is)
  2. New hardware and tech was evolving at a rate that the Linux Kernel could not keep up (again, I don't think this is am issue)
  3. The end goal is to migrate the entire Kernel to Rust.

Regarding point 3, having both C and Rust really only makes sense as a transition phase (measured in years) - as it would require kernel developers to be savvy in both C and Rust, or would force developers to stay within whatever domains were implemented in C or Rust.

From my experience knowing how both C and rust works makes you a better developer in both languages.

Learning Rust made me a better C# programmer.
