The Rust community seems to be obsessed with the idea of re-writing every prior piece of software in Rust, to such an extent that there is a specific word for it: RIIR. This is sometimes funny, since it demonstrates the incentive to be "approved", to be praised, for some reason unknown to me. And yet, I don't see much game-changing software written in Rust, such as Docker or Kubernetes.
