Scissors, Paper, Rock: 2014 Version
Cory Doctorow writes at WIRED (in a story about how restrictions on technology actually expose us to greater harm):

I recently exchanged words in an airport lounge with a late arrival who wanted to use the sole electrical plug, which I had beat him to, fair and square. "I need to charge my laptop," I said. "I need to charge my leg," he said, rolling up his pants to show me his robotic prosthesis. I surrendered the plug.

The point of the piece:

The only way to sustain HAL9000.exe and its brethren--the programs that today keep you from installing non-App Store apps on your iPhone and tomorrow will try to stop you from printing gun.stl on your 3-D printer--is to design the computer to hide them from you. And that creates vulnerabilities that make your computer susceptible to malicious hacking. Consider what happened in 2005, when Sony BMG started selling CDs laden with the notorious Sony rootkit, software designed to covertly prevent people from copying music files. Once you put one of Sony BMG's discs into your computer's CD drive, it would change your OS so that files beginning with $sys$ were invisible to the system. The CD then installed spyware that watched for attempts to rip any music CD and silently blocked them. Of course, virus writers quickly understood that millions of PCs were now blind to any file that began with $sys$ and changed the names of their viruses accordingly, putting legions of computers at risk.

Code always has flaws, and those flaws are easy for bad guys to find. But if your computer has deliberately been designed with a blind spot, the bad guys will use it to evade detection by you and your antivirus software. That's why a 3-D printer with anti-gun-printing code isn't a 3-D printer that won't print guns--the bad guys will quickly find a way around that. It's a 3-D printer that is vulnerable to hacking by malware creeps who can use your printer's "security" against you: from bricking your printer to screwing up your prints to introducing subtle structural flaws to simply hijacking the operating system and using it to stage attacks on your whole network.

...But if the world's governments continue to insist that wiretapping capacity must be built into every computer; if the state of California continues to insist that cell phones have kill switches allowing remote instructions to be executed on your phone that you can't countermand or even know about; if the entertainment industry continues to insist that the general-purpose computer must be neutered so you can't use it to watch TV the wrong way; if the World Wide Web Consortium continues to infect the core standards of the web itself to allow remote control over your computer against your wishes--then we are in deep, deep trouble.

The Internet isn't just the world's most perfect video-on-demand service. It's not simply a better way to get pornography. It's not merely a tool for planning terrorist attacks. Those are only use cases for the net; what the net is, is the nervous system of the 21st century. It's time we started acting like it.
