Ed Felten has been pointing out yet again that people who make technology policies should understand the technologies they are trying to regulate.
"DRM tries to defeat technology with technology, so faith in technology doesn’t get you very far. To make good policy, what you really need is to understand the technologies on both sides of the battle, as well as the surrounding technical landscape that lets you predict the future of the technical battle.
The political challenge here is how to defuse the dangerous instincts of the less-informed techno-utopians. How can we preserve their general faith in technology while helping them see why it won’t solve all human problems? "
