Then, after all that, come back and tell us that a modern desktop is the utilitarian endgame of OS innovation :).
Do you have other writings?
Are there any books about this?
Do you think about this often?
Some of the folks in this camp are firmly in the traditional Unix "camp" and mock cat -v, but there's a pretty refreshing diversity of views there. Some swear by the Unix Haters' Handbook, others come from (what's left of) the Amiga community.
I don't know if there's a central gathering place, but if you look around the Fediverse, IRC, various tildeverse servers, you'll eventually run into someone :).
A 1995 book that somehow ended up in my old home town's public library called Tog On Software Design, describing a project at Sun to build a desktop of the future, was one influence as a kid. Definitely check out the celebrity endorsements on Amazon.
