While I like the grand idea here — ability to interact directly with things that matter to us without having to pay attention to mediating tools — isn’t that a matter of user experience? The pen I use for drawing on a piece of paper has a sort of UI (shape, weight, friction, thickness, etc.), yet I don’t pay attention to that because using a pen feels like my writing or drawing flows directly from my mind. Messaging paradigm will undoubtedly work well for some purposes, while for others it would probably feel just very clunky.
