I definitely agree with Doctorow on the disingenuity of the phrase "Intellectual Property." And I agree with him that the creator of a particular piece of knowledge has a long-term interest in that knowledge. I don't think that the point of this article is to propose a new paradigm; rather, it introduces the idea to the general public that as a society we need to find new ways of interacting with the very idea of knowledge. The point of the article is to encourage collaborative discussion, and not yet to offer some new approach.
In the case of copyright I will note that under current laws things without physical manifestation already do not convey rights to their creator. Dances are not copyrightable. Facts are not copyrightable. Mathematics is not copyrightable. Music is not copyrightable until it is recorded. A work must have a creative element and be translated into a fixed medium to be copyrighted.
If something has no physical manifestation, can it be considered to be 'created' at all?
Doctorow is not implying that things which fall under the purview of copyright, trademark, and patenting should give no rights to their creator. In fact he argues the opposite, which is that the creator has a long-term interest in the creation which we as a society need to recognize. However, drawing analogies with exclusive physical property leads to harmful actions which become more and more abusive in this digital age.
I won't claim to have the final answer as to what the correct approach to the dissemination or control of knowledge is. But I do know that the current system of 'Intellectual Property" is broken. Our increasingly connected, digital society must reexamine its assumptions about power over and the creation of knowledge.
Part of the problem is that we don't yet have to words to frame this discussion. What should we call knowledge which required creativity to generate which recognizes the creator's engagement in the work without the contentious control implied by the word 'property'? Knowledge fixed in a digital medium is trivially copied, disseminated, and altered. The level of societal control needed to prohibit the exercise of these fundamental digital rights tramples on the liberty of the individual.
Something needs to change.
