@RtFusion: It's not fooling the brain. Stereographic projection is fooling the brain, but holography generates the same light wavefront as you'd get off an actual 3D object.

@Wolfstone is informative: The term isn't being abused at all. Modern technology has terahertz transistors, which can switch in the time it takes light to travel a fifth of a millimeter. You can buy a CPU from Intel that operates at 3.33GHz; light travels just a few centimeters during its clock tick, and it's a…

@zaghy2zy: Microsoft recently bought a company that was working on gesture controlled PC interfaces, using pretty similar technology.

@CaptainJack: And each clock cycle represents quite a lot of work too. Modern transistors are very, very quick.

@casen: For your second question, no. The IR emitter isn't much different from the IR emitter in a remote control, and those haven't made anybody blind yet.

@TheCrudMan: I remember playing that too. But it didn't know where your arms and legs were, it only knew roughly where your torso was, so you could duck in and out of cover.

@k2backhoe: [en.wikipedia.org]

@jackslackofselfrespect: The depth map comes from the IR camera, but the on-board AI that recognizes people uses information from both.

MIT was working on something similar about 10-15 years ago, although they used an acoustic system in a special material to modulate the input light, rather than modulating the laser directly.

@dml258: Your basic premise is that 'researchers are stupid and didn't consider these factors.'

@Kerensky97: I agree. Dolphins have nothing on crows.

Sodium limits are pointless. Sodium is harmless unless you've got hypertension, which small children don't.

@vinod1978: Everybody I know with a MacBook has a retail copy of Windows on it in Bootcamp. PC sales with OEM software earn Microsoft half what retail does... so I think Microsoft makes more money from your average Mac user than they do from your average PC user.

@Justin Dean Job: Disagrees.

@mattjumbo: No, it's about words. Words have meaning. Sentences have meaning that can be determined by considering the meaning of its constituent words, and how those words are connected by grammar.

And you don't really hear people talking about how the Russians lost the Crimean war anymore. But they still lost.

@latsay: Apple did lose the desktop battle. The desktop battle is not as relevant as it once was, but they still lost it.

@Odin: I remember an old economics professor talking about new technologies and the new markets that followed. His observation (which he proceeded to back up with dozens of examples) was that disruptive technologies almost always lead two one of two market situations:

You laugh, but there's a woman who got her insurance company to replace her broken computer.

@xido: Nay, you needn't walk. The ships are ready to bring you to the McLobster.
