Complex Global Supply Chains

In GigaOM:  " ...  Thanks to the growth of 3D printing, intelligent robots, and open-source hardware, tomorrow’s supply chains will be faster, smaller, cheaper, and local. ... " .   I agree that 3D printing will make strides in the near future.  3D printing technology will also allow us to differentiate items as well, minimizing what we need to ship.  Many items will thus be remotely manufactured by transmitting bits rather than entire item..   But we still need large and complex items that are composed of atoms, and get these to the right place.  Note my other explorations in this space.
