As computer technology advances, it is only a matter of time until a slice of pie can be rapidly printed using the periodic elements like a contemporary 3-d printer uses plastics. . A computer and printer can build from the molecule to the whole object. At some point we will be able to buy a code for a new product online and print it in miniutes. It is theoretically possible to print anything from an apple to another printer.... The need for centralised industry will cease to exist. As a result, the need for the infrastructure that supports it will also cease to exist. No need for ports, stores, ups.....Much of the physical architypes that we have today will become obsolete. If you think this is far fetched, take a look at how quickly a thing like netflix made the traditional video store obsolete. What are your thoughts on this. What are the social and political implications of such a change? Will the gov't eventually limit our freedom on the internet inorder to prevent someone from printing a gun or a grenade? What do you think the timeline is for this technology to reach its ultimate potential?
