I agree that robot armies are an important aspect of part II.
Why? I can easily imagine an AI takeover that works mostly through persuasion/manipulation, with physical elimination of humans coming only as an “afterthought” when AI is already effectively in control (and produced adequate replacements for humans for the purpose of physically manipulating the world). This elimination doesn’t even require an “army”, it can look like everyone agreeing to voluntary “euthanasia” (possibly not understanding its true meaning). To the extent physical force is involved, most of it might be humans against humans.
