Technology is changing the world so quickly that decentralized manufacturing is a design that has been around since the late 60s.
Unfortunately, it only existed in a Sci-Fi show called Star Trek. Not trying to sound stupid but with the 3D Printer, a person could manufacture certain goods for themselves.
Rather than have manufacturing facilities in every home we could centralize it like Walmart does a manufacturing facility for so many people, but instead of just one a bunch are built let's say 20 for every city.
With the way Blockchain technology has changed not only the internet but currency and banking as we know it. I can do the mental gymnastics required to follow the current trend for the next decade.
