Kindle Notes & Highlights
It is the duty of machines and those who design them to understand people. It is not our duty to understand the arbitrary, meaningless dictates of machines.
Why do people err? Because the designs focus upon the requirements of the system and the machines, and not upon the requirements of people.
This is sometimes called Stigler’s law: the names of famous people often get attached to ideas even though they had nothing to do with them.
Technology changes rapidly, people and culture change slowly. Or as the French put it: Plus ça change, plus c’est la même chose. The more things change, the more they are the same.
Designers need to make things that satisfy people’s needs, in terms of function, in terms of being understandable and usable, and in terms of their ability to deliver emotional satisfaction, pride, and delight. In other words, the design must be thought of as a total experience.
