There has been much uproar –obviously– because of the American guy who 3D-printed a gun and uploaded the design to the internet. There was even an interesting docu film made by Vice.
Now, the Victoria & Albert Museum bought it. Even more uproar. (Look at the aesthetics of the pic!)
The paradox was pointed out by Jonathan Jones:
"What this gun really shows is the human propensity to make the worst of its own intellectual power. Within a few years of the Wright brothers making human flight a reality, war planes took to the air. As soon as nuclear fission was achieved, it was used to destroy cities. Now, as soon as 3D printing opens up a new age of design, it is used to preach the might of the gun."
