What do you think about UI? Note: this TED Talk was presented in 2010.

View this Ted Talk presentation, and consider what the presenter expected to happen within five years from the date of the talk, and compare that expectation to where UI is today, eight years after the talk. Why haven't our UI-systems evolved in the way envisioned by Mr. Underkoffler? Do you think the reasons are/were technical, social, political, economic, or something else completely? Do you think we will eventually advance to user interface systems that are similar to his presentation? If yes, explain. If no, explain. Now that we've moved beyond the initial chapters in our text, and you've developed new insights on UI
