> I do not advise skimming That's very right, but modern life is complicated so accurately study something demand much time, quickly see the concepts might helps and well, the concept of textual-UI is definitively not alien to me, since my desktop is EXWM, with almost all my digital life in org-mode, org-roam-managed notes, it's still very different than Oberon (or Plan 9) desktop but the textual concept and org-mode links that can execute sexps on click (a feature I use much, for instance to link specific mail/threads in notes and create interactive presentations) it's similar. The 2D "spaced" desktop concept It's something I see in the far past, SUN Looking Glass LG3D concept desktop https://en.wikipedia.org/wiki/Project_Looking_Glass https://en.wikipedia.org/wiki/Project_Looking_Glass and yes while the above help they still can't tell me what's inside the package, meaning what's behind the UI concept and the language grammar. I still miss the architecture. However I suppose for what I've seen so far that essentially it's not really usable in real life so it's a nice to know project but stop here, like Lisp M Genera or Plan 9. Emacs at least can be used for real today. It's sad the IT industry have pushed what I call the glorification of ignorance, but more than preserving knowledge for a more civilized world I think we can't do. So far in the last decades most of the old valid ideas get anyway accepted, for instance widget based UIs have essentially failed and are more and more substituted by WebUIs witch are read-only DocUIs or NotebookUIs witch are limited 2D CLIs, something close to a DocUI. They are mostly text-based as well. So well, maybe in 10+ years we will finally have something like an Oberon or LispM desktop, surely returned with many anti-users aspects but still offering something of the past glory, and there memories will help to keep correcting the aim and reducing the loss. Anyway until people realize the substantial importance and role of IT there is little hope for a more civilized era...
