Many think this is not going to change EVERYTHING. I think it will as the tech improves every day. Soon distributed manufacturing will begin to be developed everywhere. One day, you want a new car, purchase the license and print the parts at a local assembly plant an pick it up in a few days. It WILL happen. Now that is has been shown that this concept is REAL, new/future variations will extend the process to harder composites (maybe carbon fiber?). There is no end in sight!
This may really help decentralize population centers and reduce the massive pollution caused by large cities. Now many of us can live about anywhere there is a good Net connection. Grow our own food (http://foody-hydroponics.com/
), conduct business (http://free-agent-services.com/
) and live healthier/longer lives. With decentralized manufacturing, off-shoring will not be necessary, just local 'assembly points for large stuff and much may be created in homes or local fabrication plants (cost of devices will be high for a while).
It is an exciting future! Now if society can somehow find some sanity, we may yet survive to colonize the Moon, Mars and beyond!
