Well, I think things will get more focused. Like Google's watch UI announced the other day, it only does a few things. Also, as voice commands start really taking off, visual UIs will fade in importance. Sure, we'll always have visuals, but it won't be so abused as described. Lastly, good UX is happening now, you see really smart people like Alan Cooper who design for goals, not just a single task. This way of thinking about an interface even before its made will cut down on some of the UI foolishness.
