Remembering some man-made disasters, and seeking to avoid them in the future.

Today is the 20th anniversary of the Chernobyl nuclear disaster. A ceremony took place at 1:23 a.m. local time in Ukraine, the exact moment that Reactor 4 exploded at the power station on April 26, 1986.

Today is also World Intellectual Property Day, the date on which the Convention establishing WIPO entered into force in 1970. The term "Intellectual Property" is used by lobbiests to narrow peoples understanding of exclusive rights such as patents, copyright and trademarks by comparing them to Lockean real property. While many people, from Thomas Jefferson onward to Tom Flanagan, have stated that intangible exclusive rights on works of the mind have very little in common with tangible real property, WIPO has successfully confused many people.

The most innovative changes as we move towards a knowledge economy, such as peer production, are possible by breaking free of this immature way of thinking of works of the mind. My own business model relies on allowing the marginal price (royalty fee) of the works of my mind to be equated to the marginal cost, which is zero. The marginal cost being zero is one of the many ways in which works of the mind are very different than Lochean private property.
