I unironically wish there was an enterprise version of Plan 9. I've been writing most of my scripts in `rc` (something my coworkers put up with because we use nix and I can pull it in automatically with dirnev) and it has been great.
It could be used to replace k8s-based deployments (also Docker Swarms, etc.) since system interfaces on Plan 9 are namespaced and containerized "out-of-the-box" as part of its basic design (and this is one of the most prominent additions compared to *NIX). It's not a hacked-on feature as with Linux.
