Was the Ak-47 not designed? Are you reading this wearing glasses? Did the combustion engine not have an impact world? Why does our toilet waste not flush out onto the street? Where those things not designed?
Am I missing the point here? How is this a discussion?
Are we only talking about communication design? If so, is typography not designed? Is propaganda not designed? How do we know how to get to the hospital — are sign posts and maps not designed? How would we know to dial and Ambulance?
This idea of design not being able to change the world sounds ludicrous to me, I cant believe that it is a debate!
