For years, the U.S. has been hemorrhaging manufacturing jobs to China because of the vastly cheaper labor pool. But now, several different technologies have ripened to the point where U.S. companies are bringing some operations back home. 3D printing, robotics, AI, and nanotechnology are all expected to dramatically change the manufacturing landscape over the next several years. From the article: "The factory assembly that the Chinese are performing is child’s play for the next generation of robots—which will soon become cheaper than human labor. Indeed, one of China’s largest manufacturers, Taiwan-based Foxconn Technology Group, announced last August that it plans to install one million robots within three years to do the work that its workers in China presently do. It found Chinese labor to be too expensive and demanding. The world’s most advanced car, the Tesla Roadster, is also being manufactured in Silicon Valley, which is one of the most expensive places in the country. Tesla can afford this because it is using robots to do the assembly. ... 3D printers can already create physical mechanical devices, medical implants, jewelry, and even clothing. The cheapest 3D printers, which print rudimentary objects, currently sell for between $500 and $1000. Soon, we will have printers for this price that can print toys and household goods. By the end of this decade, we will see 3D printers doing the small-scale production of previously labor-intensive crafts and goods. It is entirely conceivable that in the next decade we start 3D-printing buildings and electronics."
