The scenario I fear most would be AI generated opinionated podcasts aimed at humans, with the purpose of directing their preference, that is, "propagandAI". This already happens daily with traditional media, but that also gives us the weapons to fight it because there's a person on the other side and we know humans can be evil or just fail. But who is to blame when million of people put in power the wrong person because of what an AI that is not a legal person, still they deeply trust because "machines can't lie", directed them to by pushing the right buttons in their heads?
What concerns me the most isn't the AI itself but rather the humans behind it that will use it to take advantage of other humans.
