Architects and urbanists are fascinated with cities that are shrinking, like the Rust Belt cities. Or, alternatively, we are fascinated with the growth of favelas and informal settlements. The 2008 financial crisis made these changes more extreme. The subtraction protocols rehearse a way of thinking about multiple properties in counterbalancing interdependence - not just the shaping of one property but the ratcheting interplay between properties.

Few would look at a concrete highway system or an electrical grid and perceive agency in their static arrangement, spaces and urban arrangements are usually treated as collections of objects or volumes, not as actors. Yet the organization itself is active. It is doing something.

It would never occur to me to map my research against events in my life, and the recent history of globalization seems to be part of someone else's life. Still, maybe I have been trying to fill in a history or address that amnesia for the recent past. There's so much that's opaque about the ways in which extra layers of global governance have developed since Pax Americana and really accelerated in these last thirty, forty years.

Rather than asking architecture to be more interdisciplinary - a perennial issue within the discipline - I am suggesting that other disciplines might exploit the powers of architecture and urbanism. When addressing urgent situations, whether it's the depletion of the rainforest or abuse of labor, well-meaning people are working with tools, like standards, that seem like very blunt instruments. I am suggesting that spatial variables that are underexploited in governance might add to that repertoire.

The whole idea of action being a carrier of information is something that comes directly from theater. That's, in some ways, the one thing I've been trying to contribute. I still write things outside of architecture - not really fiction, but not nonfiction. I like dialogue as a form, because the text is only the trace of an action. The consequential information is carried in the action you choose to put on that text.

In architecture, to do anything beyond object form is often treated as something extra-disciplinary - something outside the discipline that has nothing to do with art. So I'm making it clear that this is an artistic choice. It's not everyone's artistic choice. Some people should choose only to make object form because that's what gives them pleasure. But there are people for whom aesthetic pleasure comes from doing something else, and why would you deny that choice? It's another autonomous choice.

It wasn't an architect who did this, but if it had been an architect, it would have been a good day's work: there was a marketing person who convinced Walmart that their products sold better in daylight than electric light. It would have been interesting if an architect had deliberately designed this change with all its spatial consequences in mind, thinking about how the change would multiply across all the square footage of all the roofs of all the Walmarts in the world. It would have been a beautiful trick - a physical, practical, political pleasure.
