Here's Linus' take:

  You need to realize that  
  
  (a) reality trumps fantasy  
  
  (b) kernel needs trump any Rust needs  
  
  And the reality is that there are no absolute guarantees. Ever. The "Rust is safe" is not some kind of absolute guarantee of code safety. Never has been. Anybody who believes that should probably re-take their kindergarten year, and stop believing in the Easter bunny and Santa Claus.

  If you cannot get over the fact that the kernel may have other requirements that trump any language standards, we really can't work together.
