I think the main problem of Unix today is that it's not Unix-style enough. Too many namespaces with too many non-composable separate APIs on them instead of "everything is a file". Plan9 is more Unix than Unix and that's indeed better. Redox OS, too.

The Unix security model is mostly useless today, but it seems like something better is possible as an incremental change, and there are projects that do that, like RSBAC.

Yes, "everything is a file" but the mouse on Rio is written in stone.

Aside of that, plan9 wins on the theoretical side, it was a research OS, but in the practical one... it's opinionated.
