Yochai Benkler, a law professor at Yale University, has called this "commons-based peer production." The commons refers to the sharing of the underlying code or the output that is open to all, akin to the public land that farmers once grazed their livestock upon. Peer production means that producers participate for their own varied reasons and in ad hoc ways, not necessarily via legal contract or management fiat. Benkler calls this a third mode of production for the market, distinct from the company and the "spot market" (or, in employment terms, the freelancer). Open source shows that it is possible for part of the economy to function without companies but with many self-employed individuals contracting with each other.

And then Chenoweth has found, looking at the accounts, that the company’s profits, declared in Australian dollars, were A$364,364,000 in 1987, A$464,464,000 in 1988, A$496,496,000 in 1989 and A$282,282,000 in 1990. The odds that such figures were a happy coincidence are 1,000,000,000,000 to one. That little grace note in the sums is accountant-speak for ‘Fuck you.’ Faced with this level of financial wizardry, all the ordinary taxpayer can do is cry ‘Bravo l’artiste!’

IT WAS beautiful, complex and wrong. In 150AD, Ptolemy of Alexandria published his theory of epicycles—the idea that the moon, the sun and the planets moved in circles which were moving in circles which were moving in circles around the Earth. This theory explained the motion of celestial objects to an astonishing degree of precision. It was, however, what computer programmers call a kludge: a dirty, inelegant solution. Some 1,500 years later, Johannes Kepler, a German astronomer, replaced the whole complex edifice with three simple laws.

Some people think modern astronomy is based on a kludge similar to Ptolemy's. At the moment, the received wisdom is that the obvious stuff in the universe—stars, planets, gas clouds and so on—is actually only 4% of its total content. About another quarter is so-called cold, dark matter, which is made of different particles from the familiar sort of matter, and can interact with the latter only via gravity. The remaining 70% is even stranger. It is known as dark energy, and acts to push the universe apart. However, the existence of cold, dark matter and dark energy has to be inferred from their effects on the visible, familiar stuff. If something else is actually causing those effects, the whole theoretical edifice would come crashing down.
