Kahn speaks of light and its importance in architecture and how architecture is dictated by basic laws. Tenets such as door frames being large enough to fit a human and the wheel on a cart being circular. Gershenfeld talks of computers and their evolution, concepts and realities of personal fabrication tools, and the division between owners and workers separated by resource availability. Both Kahn and Gershenfeld see the desire in humans to create. Kahn sited dissension to the norm as being the impetus while Gershenfeld sees creativity existing in people. Gershenfeld was surprised at the response to the PFT program.
