Develop a global ethic over national self-interest and argues that the massive changes in technology

In his TED talk, Gordon Brown discusses the need to develop a global ethic over national self-interest and argues that the “massive changes in technology” will lead to more people across the globe interacting with each other and therefore we will better recognize our responsibilities to others. As the events of the past few years have shown, this has not turned out to be the case. Britain is no longer part of the European Union after the so-called “Brexit” vote and across the world existing associations are splintering. Why do you think that even though communication across the globe has increased, countries are becoming more insular and protectionist?
