A recent and upcoming history of computing interfaces:
GUI --> Haptics/Gesture + Voice --> Brain-Computer Interface + AI
The haptics, gesture, and voice interfaces allow a much more natural physical interaction with our computers. People are going to really enjoy transitioning from mouse and keyboard inputs to interfaces like Apple's iPhone and Microsoft's Surface. Add in a little voice recognition and interfacing becomes fun again.
Of course, the only interface technology left will send all data directly into your brain. Add in some AI friends...
Well, let's just enjoy this current interface revolution.
