Filmmaker Adam Curtis questions the value of Big Data in society. In his latest BBC series, 'Can't Get You Out Of My Head', Curtis explores "Love, power, money, ghosts of empire, conspiracies, artificial intelligence – and You." Curtis spoke to Business Daily's Ed Butler about how the rise of artificial intelligence, Big Data and targeted advertising have come to shape the way we see our world and caused us to feel helpless within it. He also explains that the psychological experiments which underpin our faith in the effectiveness of such technologies might not be as reliable as once thought, which Curtis says gives us some cause for hope.
