DGC on DSC

Is time travel possible? What if we printed new organs like a document? What if cars drove themselves? Well, I don't know much about the first two questions, but I have a little something to say about the last one. Watch CUDGC trip over the cutting edge of technology and fall face-first into the future in "Update 2057: The World in Fifty Years." The special airs on the Discovery Channel on January 28, 2007 from 8pm to 11pm.
