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.

There is a comfort with design that may be a detail, rather than a building; comfort with form that is time-released and never finished. How do you represent an instruction set that will play out in time? There may be slightly different kinds of documents for representing those forms, and different skills for advocating change outside of our fee-for-service habits.

It's funny how much one learns from context. Throughout that entire visit to Kenya, with all its meetings, there was an experience of the place that taught me things I couldn't learn by reading global newswires. The fact that I learned so much makes me wish that I could visit more places. So many of the zones, of course, are closed, so one knows about them only in secondhand ways. My research has only scratched the surface. There are thousands of zones around the world. There's just so much work to do.

It may be unfathomable in architecture, but it is very practical, or routine, for a person in theater to use action. You have the line, "Come home, son," but you can't play that line by going out and being a mother; you can't be a noun. But you can play to smother your son; you can play to grovel to your son. Again, the real information is carried in action. And, to an annoying degree, theater people talk to each other in infinitive expressions. If you don't have a vivid verb to describe what you're doing, you're probably going to be a pretty bad actress.

Whether railroads or electricity or the Internet, there is always some sense that this is the new, redemptive platform - that finally, finally, we've found the platform that will allow us all to lead a democratic, global existence, where all problems will be solved. And the idea that the old platform becomes obsolete, "this kills that," and so on, also often accompanies the advent of a new technology. The digital platform is no exception.

I love making object form; I wish I was doing more of it. I admire the research of my colleagues, and sometimes it makes me sad when their beautiful work - the deep dives into formal research and nuances of geometry and so on - ends up circling in more and more circumscribed contexts. I wish they were more powerful. It's not a modern proposition. Active form doesn't kill object form. I want my students to have all those skills related to geometry, shape, measure, scale, etc., plus skills for using space to manipulate power in the world.

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.
