I haven't read this yet, but it seemed interesting.

Earlier this week, the American Enterprise Institute in Washington, DC, held a remarkably interesting conference titled "Panic Attack: The New Precautionary Culture, the Politics of Fear, and the Risks to Innovation." It was interesting not only because I was a participant, but because it looked at how many Western countries are losing their cultural nerve, as evidenced by the increasing cultural acceptance of the so-called precautionary principle.

The strongest versions of the precautionary principle demand that innovators prove that their inventions will never cause harm before they are allowed to deploy or sell them. In other words, if an action might cause harm, then inaction is preferable. The problem is that all new activities, especially those involving scientific research and technological innovation, always carry some risks. Attempting to avoid all risk is a recipe for technological and economic stagnation.

Bill Joy came to mind.
