"Every technical improvement by lowering costs and perfect utilization of materials and power, bars the way to further progress. There is less left to improve, and this narrowing of possibilities results in a slackening or complete cessation of technical development."
"... sooner or later, every paradigm begins to develop a very special set of problems that everyone in the field wants to be able to solve and no one has a clue as to how to do it."
"A radically new technology does more than merely perform old functions better; it makes it possible to perform functions that the technology it replaces could not do at all. It not only solves a problem, it over solves it."
