It's a little weird that we can induce addiction remotely, through the sense of vision, using purely computational means. Maybe not as weird as memes, but close

It's a little weird that we can induce addiction remotely, through the sense of vision, using purely computational means. Maybe not as weird as memes, but close. By putting a person and a neural net in a control loop, I wonder how much you can influence, say, their hormone levels. Surely the media have been hacking fear-attention and cortisol for a long time. But what happens as this becomes even more automated? We'll be like those Australian beetles, if we aren't already.
