So this is an interesting essay on projections of interaction design in the near future: http://worrydream.com/ABriefRantOnTheFutureOfInteractionDesign/
It's worth reading the full thing, because I think it highlights something interesting about humanity's perception of the future. The future is the newest thing now, but put in more places. It's a good thought for taking the latest trend and trying ot make it ubiquitous (and there is innovation there), but it doesn't lay out the future.
The future, the new, the shiny. That's something that isn't here yet. When Apple purchased Siri 2 years ago, that's because they thought and think that future interfaces will be primarily voice driven, or that voice will be a large component of it. Bret sketches out where else we might go, and why we might want to go there.
