So many "new interface" ideas seem to forget that a large percentage of what people use computers for is in offices, producing documentation. Using your voice, or spinning 3D interfaces around with your hands, just isn't practical in an office environment with dozens of people working, where you are essentially outputting text. Until that basic reality changes, I don't think mainstream computing needs will change. Along the same lines, I don't think the reverse is feasible, with computing interface changes bringing about social changes. The shifts we've seen from hand-writing to type-writing to computer-based word-processing has been happening in roughly the same environment for a very long time.
