When we have this description, of what a sketch is, itsattributes, we can then start inventing new things thatshare those attributes, and therefore improve our currenttechnics by inventing new and better tools that help ussketch.
My thesis [is] that in order to design a tool, we must make our best efforts to understand the larger social and physical context within which it is intended to function
If history is any indication, we should assume that any technology that is going to have a significant impact over the next 10 years is already 10 years old!
