Have you ever stayed 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.
This law shows that tasks in project management and daily life often take longer than anticipated. For example, in software development, unexpected delays can occur due to changes in specifications or technical challenges. Similarly, in personal task management, daily chores and studying can take more time than we 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.
The expression "planning takes longer than expected, even if you consider Hofstadter's Law" symbolizes the essence of this law.
