“We are more connected than ever, but it also makes it easier for us to retract in small tribes, to be confined in its own bubble. We never question, we challenge our own premises because everything we read, we only hear people who think just like us, simply because an algorithm has decided that it should be so. We have to cultivate independent journalism. We have to react to new forms of propaganda. We have to listen to people who disagree with us. ‘ B. Obama, Global Citizens Forum, SP Brazil
