What is Design? A question with no real answer, and one that seems almost preposterous to ask and expect a clear answer. And yet we insist, as part of an annual tradition and ongoing research into exactly what design can be, across different domains and cultures. Rather than trying to divine a definitive answer or secret truth, What is Design? simply documents some possibilities of design in a certain moment in time and space. Collectively, these interviews allow us to continue building and expanding that definition, and inspiring others to think differently about what design can be and how it can continue to evolve in the future.
