And to design is to take purpose into account — as my friend Jared Spool says: design is the rendering of intent. You can’t separate an object’s function from its intent. You cannot critique it, you cannot understand it, and you cannot appreciate something without thinking about its intent. You are responsible for what you put into the world. And you are responsible for how what you’ve designed affects the world. Mikhail Kalashnikov is responsible for as many deaths as the people who pulled those triggers.
