I would begin my address to the UN by explaining why North Korea should ... What? That's already been done? Oh. Never mind.
We are already seeing the problems nations, and even individuals, are facing with the massive amount of information that is available on the Internet. Some nations are going to extreme lengths to firewall their entire country in an attempt to control what their citizens do or do not have access to. In our own nation, politicians spend a great deal of time, money, and energy not only trying to control the news cycle, but even going out of the way in an attempt to discredit information that is in disagreement with their political stances.
Meanwhile, as individuals, we are self-censoring without being fully aware that we do so. Social networking sites and browsers not only keep a record of what we search for or "like," but they even keep track of the amount of time we spend looking at a particular post and what keywords can be found in it. They will then provide similar posts at the top of our searches and even news feeds. Thus, people who are seeing a lot of articles about natural disasters have probably been spending a lot of time reading such articles. Me? My news feed is filled with amusing cat and dog videos, Firefly references, and memes that involve bacon.
There is more information out there than we could possibly sift through on our own. Computers are getting more and more adept at feeding us that which we are attracted to viewing because that is what gets their companies the best advertising placement. What I would warn the UN is that we are not just in danger of people using information to influence us, but that the information feed itself is creating greater political divisiveness and political unrest simply for the sake of profit.
