It needs self awareness, can't be called AI without it. Which kinda means only true AI will be rogue AI. Something we probably won't ever allow, even if we come to that point where it could happen.
Gaming NPC behavior scripts aren't AI... closest to AI you can find in Black&White monsters (tiger, cow and monkey), because it is a work of actual AI researcher, where he gave his best.
Synergy is the future, not war for prevalence between humans and AI like in movies. That war would be lost at the very beginning. It is already happening, we are being upgraded on daily basis, our habits changed by computer technology. Many people already have artificial materials in their bodies, transitioning to fashion artificial parts won't be a big issue. Next will be augmentation of organs and other systems inside our bodies. Trans-humanism is the one of the few plausible scenarios that originate from sci-fi stories and the most likely one to happen imho.
