I believe some magical self aware AI isn't worth the fear. The real AI we have now is already destroying society. It is more commonly referred to as boring old machine learning. It is a dangerous weapon which has replaced all the "think tanks". You collect data for it, and propose talking points and political moves and it will tell what percent of the population will accept being being put into cages without opposition, based on those. It is the reason why people fall for such dumb nonsense; they have weaponized exploiting the public, their fears, their lack of knowledge, and their easily manipulated minds. When google knows what news you've seen, what books you've read, what videos you've watched, then sell that to those who would pump that data into machine learning, then they know what you know and can predict how you might respond to situations based on that.
