Isn't Notion pretty close to what's being described here? Sort of weird combination of networked spreadsheet, relational database, writing + notetaking app? There's been an explosion of competitors and imitators, too. Some, like Roam, definitely have a utopian 1980s hypertext ethos.
Lotus Agenda for example would take your notes and automatically categorize them based on the categories you created in the earlier not taking process, allowing you to filter your notes by different "views" with no input on your end (after the initial category creation). For example you could mention a contact in a Task or Note and then that note would appear under the view for that contact automatically. Etc.
