I don't think it will go full autonomous enemy of humankind entity but it will be far more insidious, targeted, embedded, data-driven, inference+kill engine. Just one scenario: a tiny drone programmed to look for certain characteristics and autonomously complete its mission with only a probability percentage number and maybe a target signal to serve as extra training data.The drone can be launching a missile to take out a village or shooting a poisoned dart in the neck, and they could number in ones or millions.
The underlying danger is that the moral agency is further and further stratified to just a handful of people instead of at least hundreds of thousands of soldiers at a visible level now. So, a small senate committee can ask a secret three letter agency to do far more havoc than a war, and we would be insensitive to it. As it is, drones are killing weekly and we are largely uncaring. The dehumanization of humankind and being reduced to just a bio-chemical material is the tragic path we are on.
