These are the expressions of what Marcus du Sautoy calls 'the creativity code'. Yet some believe that the new developments in AI and machine learning are so sophisticated that they can learn what it means to be human - that they can crack the code. Technology has always allowed us to extend our understanding of being human. But will the new tools of AI allow to us to create in different ways? Could recent developments in AI and machine learning also mean that it is no longer just human beings who can create art? And creativity, like consciousness, is one of those words that is hard to pin down: what is it that we are challenging these machines to do? In The Creativity Code, Marcus du Sautoy examines what these new developments might mean, for both the creative arts and his own subject, mathematics. From the Turing test to AlphaGo, are there limits to what algorithms can achieve, or might they be able to perfectly mimic human creativity? And what's more, could they help Marcus to see more deeply into the complex mathematical problems with which he so often wrestles?
