These electric unicycles, and other designs like them, are now only $300, thanks to factories in China that brought the prices down. Also, all of those fancy flying drones that the kids have are made possible by China. Well, to be more accurate, the U.S. military and tech companies made the innovations, and now China is mass producing them.
All of a sudden, those gadgets once only dreamed about by Sci-Fi writers have become a reality. Smaller powerful batteries, better computer circuits, computer hacking and IP theft, and Apple teaching China how to make tech stuff, have made it all possible.
