"Any sufficiently advanced technology is indistinguishable from magic." - Arthur C. ClarkeComing soon: voiceless phone calls. The implications, described in the latter half of this video, are astonishing. First, the ability to hold a cell phone conversation without speaking out loud. Second, the ability to silently request information from the Internet, on the go, and have the Internet return information to you.
I for one welcome silent phone calls on our streets and in our cafes. And the ability to access the Internet directly in this fashion would be a great way to augment my already failing memory.
Of course, it's also another step towards humanity's perhaps inevitable merging with "machines" or technology. As others have pointed out, we won't be replaced by robots or taken over by them. We'll probably be indistinguishable from them before that ever happens.
