I was thinking recently there is some sort of correlation between cryptocurrencies and 3d printing. If you think about this two, relatively new technologies, it seems like they are going in the same direction : Bitcoin is decentralizing money, 3d printers are decentralizing production. As a follower of both i would really like a world where you can buy everything (from a glass to a nuclear weapon  ) as a 3d printer project using BTC and then produce it with my own printer.

What do you think ? We are heading to a decentralization of the whole economy ? Is this good or dangerous ? /discuss
