"Guns don't kill people, AIs kill people" is where we are going, I think. This is the discussion: "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war."
The discussion is not about a mathematical representation of AI. The discussion is about the actual implementation of AI on physical computing infrastructure which is accessible by at least one human on planet earth.
The credible danger, argued in various places, including superintelligence by Nick Bostrom, is that the "system under review" here is "every physical system on planet earth" because an AI could gain access to whatever systems exist on said planet, including human minds (see "Nazis").
So much as we might discuss the problems of letting a madman get control of the US, Russian, UK, French or Chinese nuclear arsenals, we might discuss the problem of building an AI if the act of building the AI could result in it taking over the nuclear arsenals of those countries and using it against humans. That takeover might involve convincing a human it should do it.
