I went down to bare basics in my thoughts: what do we need for an exchange between machines and brains: data bidirectional and commands from human to machine. A surface is basically data + commands. Add some minimalistic styling free horizontal, vertical and z-level stacking plus some stereotypes and you can meaningful interact. The trick now is: rendering in fancy UI can be either provided by a designer (the old dream) or by an AI/algorithm depending on the actual UI (voice, screen, small screen, console, ...) either by smartness or by learning from how the users arrange the output. But never by the program/developer itself. When you look at the scifi designs .. you will realize: very simple UI (ok they never cover complex shit, but at least they have an idea how to simple do stuff)
