Graphics, User Interfaces Within the last few days we read the news about Apple's Siri AI personal assistant, and about a brain implant that lets monkeys control virtual limps & feel virtual objects. I believe that if someone is to also combine a few more technologies (e.g. high-res eyeware, appropriate operating system changes), we will be looking at the next user interface revolution, after the inventions of the computer mouse and touch interfaces.

Not holography

There are two ways to deal with the problem. One, is holographic projected displays. Unfortunately, we’re far away technologically from something like it, and no one really wants to see your huge display in the middle of the street, while you're trying to get directions

Cheap scifi film effects unfortunately totally hijacked the meaning of the word "holographic" over the decades, so the public imagines ...roughly this "huge display in the middle of the street" or, generally, what really seems more like a volumetric display (usually while projecting somebody in "scifi videoconferencing")

But that is NOT holography; the word has very specific meaning. And, sadly, people don't even realize how impressive real, already actually existing holograms feel (one rapidly found example http://www.youtube.com/watch?v=Xp7BP00LuA4 another nice one http://www.youtube.com/watch?v=6AVAzGQMxEg ), basically for a few decades already; people seem to not realize about them to the point of doubting what they see on such videos, thinking it's just a trick (no, it's not... they feel awesome when held, the light actually really behaving like the plate has some "inside")

Yes, static so far, also with poor colour gamut and such. Good holographic video display will require effective size of pixels comparable to the wavelength of light, plus processing and memory we're nowhere near yet.
But once we're there... a display will feel kinda like a window or mirror (bonus: at that point, we probably won't have to endure any more the efforts, every 2 decades or so despite numerous failures, to push on us the cheap and inherently flawed trick of stereography)

All this essentially being an example of the unfortunate effects of "scifi cargo cultism" that I sometimes point out - fluffy fantasies displacing, masking, causing the people to miss the wild possibilities in actually existing universe.
