Given the recent appalling events in Aurora, Colorado, there’s been a renewed call for greater gun control and a ban on assault weapons.
I’m in favor of tighter gun control and a ban on weapons that are unnecessarily powerful but I’m afraid that technology will soon make any legislation that limits the availability of any kinds of guns ineffective.
To understand why this might happen, you need to understand a technology called 3D printing.
3D printing allows you to build things that are, as the name implies, three dimensional. A few years ago 3D printers were very rare, hugely expensive, and hard to use. But as with anything that can be driven by computers, 3D printers has become cheaper and cheaper to the point where, today, you can buy a 3D printer, off the shelf, for as little $500.
