Primavera De Filippi & Peter Troxler [4] From material scarcity to arti8cial abundance – The case of FabLabs and 3D printing technologies Primavera De Filippi & Peter Troxler 1. Introduction Digital media allowed for the emergence of new artistic practices and innovative modes of production. In particular, the advent of Internet and digital technologies drastically enhanced the ability for multiple au- thors to collaborate towards the creation of large-scale collaborative works, which stand in contrast to the traditional understanding that artistic production is essentially an individual activity. The signi6cance of these practices in the physical world is illustrated by the recent deployment of FabLabs (Fabrication Laboratories), that employ innovative technologies – such as, most notably, 3D printing, which is recently gaining the most interest – to encourage the development of new methods of artistic production based on participation and interaction between peers. -

De Filippi & Tréguer
May 2014 Expanding the Internet Commons : The Subversive Potential of Wireless Community Networks by Primavera De Filippi1 and Félix Tréguer2 “Freedom is fostered when the means of communication are dispersed, decentralized, and easily available, as are printing presses and microcomputers. Central control is more likely when the means of communication are concentrated, monopolized, and scarce, as are great networks,” wrote professor Ithiel de Sola Pool (1984), an American political scientist and legal analyst of communications technologies. Beyond highlighting historical and technical trends in technology, Sola Pool also understood that there was nothing deterministic about how technologies evolve. While control over printing presses and microcomputers can, as it turns out, be highly centralized, the deployment and management of telecommunication networks can, eventually, undergo a process of decentralization. The outcome ultimately depends on political, technical, economic, institutional and legal arrangements shaping both the development of communications tools and their use. Often, when it comes to politics – and Internet policy is obviously no exception – the antagonism between freedom and control essentially comes down to the trade-off between centralization or decentralization. In the past year, the ongoing controversy regarding the massive surveillance undertaken by the US National Security Agency (NSA) and its allied organizations has encouraged a growing number of technology activists to deploy decentralized and free software3 alternatives to the centralized online services known to collaborate with the NSA. This trend can be likened to what happened repeatedly in the history of the Internet. The rise of the personal computer and the widespread adoption of the Internet network came out of a need to democratize computing technologies by taking them out of the hands of technocracy – decentralizing both the use of computers and the control of communication technologies. -

Blockchain Technology As a Regulatory Technology from Code Is Law to Law Is Code
Blockchain Technology as a Regulatory Technology From Code is Law to Law is Code Primavera De Filippi1 & Samer Hassan2 1CERSA/CNRS & Berkman Center for Internet and Society, Harvard University 2Universidad Complutense de Madrid & Berkman Center for Internet and Society, Harvard University Abstract: “Code is law” refers to the idea that, with the advent of digital technology, code has progressively established itself as the predominant way to regulate the behavior of Internet users. Yet, while computer code can enforce rules more efficiently than legal code, it also comes with a series of limitations, mostly because it is difficult to transpose the ambiguity and flexibility of legal rules into a formalized language which can be interpreted by a machine. With the advent of blockchain technology and associated smart contracts, code is assuming an even stronger role in regulating people’s interactions over the Internet, as many contractual transactions get transposed into smart contract code. In this paper, we describe the shift from the traditional notion of “code is law” (i.e. code having the effect of law) to the new conception of “law is code” (i.e. law being defined as code). Introduction There are various ways in which law and technology can influence each other. The two interact through a complex system of dependencies and interdependencies, as both contribute (to a greater or lesser extent) to regulate the behavior of individuals. With the advent of modern information and communication technology, the relationship between the two has significantly evolved, as the latter is increasingly used as a complement or a supplement to the former. -
