Infrastructural Fields

One of my favorite journals, Quaderns has posted an essay that I wrote for them a year ago, entitled "Infrastructural Fields." There, I make the argument that architects need to embrace the new, invisible world of Hertzian space as they design. What are the tools by which we will do this? How will we create an architecture that, as Toyo Ito once stated, can float between the physical and the virtual world? If Ito set out to do this in the Sendai Mediatheque, why have architects been so reluctant to go further?
