Abstract
The area of complexity lower bounds is concerned with proving impossibility results for bounded-resource computation. In spite of its apparent weaknesses, the ancient method of diagonalization has played a key role in recent lower bounds. This short article briefly recalls diagonalization along with its strengths and weaknesses, and describes a little about how diagonalization has made a recent comeback in complexity theory (although many would argue that it never really went away).
