“I’m attending a small private gathering and the head of MIT’s fab lab (3d printing, molecular machines, etc) replied to a comment about whether it will affect guns on the black market. He said no, because people have been building guns for hundreds of years already and they are available on every street corner. As such, that need is already met and 3D printers will be used to fill another need. It was quite a surprise to hear that from MIT.”
