The brilliant minds over at The Onion have answered this question. I just ran across this video and it gave me a good chuckle. I hope you like it also.
I just ran across a cool video of a flying robot playing Jingle Bells on an electric piano. The tempo seemed a bit off, so I clicked through to YouTube to see if there were any more videos. A link for how it works popped up, so naturally I clicked it. Base off of the video, it looks like a human was controlling the robot, so not as impressive as I initially thought. They show some background on “co-pilot” routines that assist the human controllers to keep them from making mistakes. I find this interesting because eventually with AI, these little machines could be completely automated. This reminds me of the creepy surveillance robots from Dark Angel. With special routines to keep these from bumping into obstacles, I can definitely see them flying around our cities sometime in the near future. If you want to see the Jingle Bells video, click through the via link at the bottom. I found this video more interesting though.
I just StumbledUpon an interesting article about a new type of printer that can make 3D objects. You can use various materials as input ranging from plastics to chocolate if you wanted. This device reminded me of the Matter Compiler in The Diamond Age which I reviewed recently. This is still a primitive technology, but I wonder if what Neal Stephenson envisioned might ever come true. Check out the original site to watch a brief video demonstration of the device.
