What is don't get about the AGI speculation is.. to me I can't really figure out how an AGI could exist on current computers. I can imagine AGI in robots more easily. On conventional computers I think AGI,or its servants would need to be distributed across multiple machines with either a central hub orchestrating them or some p2p system. But on some single devs machine, which is the Hollywood style, I have a hard time seeing it. Edit: and the medium for its impacting the world would be the internet. Shutting down the interconnectedness of our tech and infrastructure should perhaps pull the plug on the AGI. But the more interconnected our civ is via internet, a bit of omnipresent piece of software could resist being rooted out and could technically subvert human intentions
