Check out this recent video from the FuturICT group in which Paul Lukowicz presents his take on the project from the perspective of a computer scientist.
A lot of the issues we have been discussing come up very explicitly in this bit. Particularly interesting, I think, is how emergent structures on the one hand and purposefully built infrastructure on the other are being renegotiated conceptually, and how both are finally associated with the use of a platform by an potentially infinite and yet unkown set of users: “there will be an infrastructure” which all kinds of people may contribute to, may use to run their own projects on, built their own apps, and so on. This particular aspect of infrastructure as platform may be worth exploring further, as it has all kinds of conceptual implications, and an interesting political undertone.
A couple of more videos are linked at the site, for example a ten-minute promo of the project.
