What a fun topic. I immediately thought of a lot of things that would be too much for the time frame. I went to uni in Sweden and found the students to be very independent and proficient in their use of tech, but the battle between lagom, jante and an interest in achievement was an interesting internal conflict I noticed. While I am aware that Scandinavia encompasses more than Sweden, I think this might still be applicable.
There is a difference between theory and practice. Sure the government may have a theoretical role to protect people, but that protective role is put into practice by imperfect people. The electronic systems that are intended to remove human errors are still created by imperfect people. Positions with access to privileged information is enticing to those that are power hungry. How can you guarantee they will not abuse their position? Members/parties/coalitions of the government change which means there is a chance that there can be an increase in the less trustworthy individuals in position to be practicing that protective role.
Questioning influence is the underlying issue I think. The audience may be have some awareness about the dangers of corporations having data that can be used to nudge, influence or manipulate people. How much does the government rely on corporations to do that protective work? From where does their distinction between corporation and government come? How many of the audience members get their information directly from a news source as opposed to social media/aggregate feeds generated by a corporation? If they rely on an algorithm to feed them information they are allowing another entity to have unchecked influence. If they were to visit a variety of news sources directly, they will actually be in a position to make more independent choices for themselves rather than being led by the nose toward whatever those that control the algorithm want. The Swedes I know are responsible and independent in the way they live their lives. Pointing out questioning information sources may be a slight tweak to their understanding of being a responsible individual.
I hope your presentation is a success.
