I may have to agree with both Quiet and Suze on that; yes, 3D printing and similar technology can potentially remove the need for human labor on any one project...but no current technology, 3D Printer included, can do all the work (simply because there are not enough resources on the planet to do so). I am skeptical that most modern technology will ever be available to the world population. (An example being that the entire internet community is still a minority in relation to the overall population)
