Linguist and political activist Noam Chomsky remains as vigorous as ever at the age of 84. His popularity - or notoriety as some would say - endures because he is still criticising politicians, business leaders and other powerful figures for not acting in the public's best interest. At the heart of Chomsky's work is examining the ways elites use their power to control millions of people, and pushing the public to resist. In this episode of Talk to Al Jazeera, Noam Chomsky sits down with Rosiland Jordan to talk about the two main tracks of his life: research and political activism.
