It's funny I had almost this exact conversation with Singularitarians 10+ years ago. Killer robots sell copy, whereas more realistic evaluations of the role of technology in society are much less glamorous and get into issues which powerful people are uncomfortable with discussing."I feel like I’m lecturing you, and I am. I unequivocally am lecturing you. You deserve to be lectured right now. You’re a person in a position of power who could effect real change, and instead, you’re creating more noise and fear about a thing that’s never going to happen."
