Except unix nowadays is just a set of concepts and conventions incorporated into modern OSs
The transition happened to the huffing and puffing/kicking and screaming of many sysadmins.
This means Linux has "made it."

I guess that grit was a gateway to a basic Linux experience for a long time - it did take a lot of effort to get a normal desktop running in the early to mid 90's. But that was never going to last - technical people tend to solve problems and open source means they're going to be available to anyone. There are new frontiers to apply the grit.
