I don't think the GUI goes away anytime soon, and I don't think that is what you meant either. People are visual beings, so I think the interaction gets smaller, or more integrated into our lives. I would love something akin to a contact lens that lets us see the GUI, and a computer that responds via voice. So to me, GUI doesn't go away, how we interact and how we view that GUI does. A contact lens, brain implant all seem reasonable, but I would assume the natural progression will be hardware wearables, then biological wearables (contacts etc), then implantations.
