Define "mainstream." This gives the false idea that such an interface would take over the way humans normally compute and interact with machines. This interface is nowhere close to the level of replacing the traditional keyboard/mouse or the emerging multitouch tablet. People simply cannot interact with textual data quickly enough and would easily get tired with that interface. I can code at my keyboard/mouse for 10-30 hours straight without much fatigue. I wouldn't last 30 minutes on that thing. Nevertheless, it's really cool and I can't wait to see future interface designs. Just don't make the lofty claim that it will be "mainstream." (just a personal opinion)
