Have you ever experienced staying up for three days before a deadline? No matter how carefully you plan, things often do not go as expected. This phenomenon is known as Hofstadter's Law, proposed by Douglas Hofstadter in 1979.
Hofstadter's Law shows that projects and daily tasks often take more time than anticipated. For example, in system development, unexpected delays can occur due to changes in specifications or technical issues. Similarly, in personal task management, household chores and studying can take longer than you expect.
In the history of chess development, it was predicted that "computers will surpass professional players in ten years," but this did not happen until eighteen years later. Ironically, Hofstadter's own words, "Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law," perfectly capture this idea.
