Time and the Web

Modern user interface paradigms depend on direct manipulation, rapid response and immediate semantic feedback. Up until the early 80s response time was a recognized problem. But, with the advent of personal computing and graphical interfaces, user interface designers have often assumed that machines will be fast enough. Response delays were no longer an interesting problem, ever faster computers would make the problem go away. I have previously called this assumption the "myth of the infinitely fast machine" [ 1].
