In futures studies and the history of technology, accelerating change is a perceived increase in the rate of technological change throughout history, which may suggest faster and more profound change in the future and it may or may not be accompanied by equally profound social and cultural change. While many scholars have suggested accelerating change, the popularity of this theory in modern times is closely associated with various advocates of the technological singularity, including Vernor Vinge and Ray Kurzweil, among others.
