It seems like it's about every other week that I read about a girl in Florida that blows up a soda bottle in school, a boy in Kentucky shooting his sister,
or (in the news earlier today) a farmer in the Philippines accidentally killing his daughter while cleaning his shotgun, then turning the gun on himself.

Stupidity knows no borders or colors, and we're all sadly affected with it.

I don't believe 3D printers would ever be banned, based on the principle of technology we're using every day.
The Internet is an information super highway for any illegal activity imaginable, ranging widely between the sale of drugs, human trafficking, contract killings and child pornography to international terrorism. Banning the Internet would only cause people to get creative elsewhere, which would be impossible to control. Same with 3D printers.

I expect that governments would much prefer to watch certain flagged webspaces where they know people can obtain dangerous blueprints for their printers, or require users to register their printers at the time of purchase.

Considering that Microsoft lost money for each and every Xbox-console they sold, and the fact that most people who chip their console choose to download games, I'd say that Mr.Gates doesn't like the pirates very much.

Does anyone know approximately how many percent of the sold Xboxes that have been chipped?
