The design of artifacts versus the design of systems. If all of these natural collapses have demonstrated one thing, it's that we are no longer living in a world of objects and things, but rather in a world of flows and negotiations. Undoubtedly this was always the case, but the feedback we're getting from the natural world has made it unassailable. In the old design model, we had 'problems' and we had 'solutions.' A designer's job was to take a problem—a brief, a market need, a new technology looking for an embodiment—and to solve it: Here's the problem; here's a solution. Next problem please.
