As we begin seeing robots/computers that are more human-like
It's not at all clear that a AGI will be human-like, anyone than humans are dog-like.
BTW, I'm curious to hear more about the mechanics of your scenario. The AGI hacks itself onto every (Internet-connected) computer in the world. Then what?
How do you fight the AGI past that point?
It controls total global communication flow. It can play out different humans against each other till it effectively rules the world. After it has total political control it can move more and more resources to itself.
Maybe it would increase chances of nuclear war, especially if the AGI could infect nuclear-warhead-related computer systems.
That's not even needed. You just need to set up a bunch of convincing false flag attacks that implicate Pakistan attacking India.
A clever AI might provoke such conflicts to distract humans from fighting it.
Don't underrate how a smart AI can fight conflicts. Having no Akrasia, no need for sleep, the ability to self replicate your mind and being able to plan very complex conflicts rationally are valuable for fighting conflicts.
For the AGI it's even enough to get political control over a few countries will the other countries have their economy collapse due to lack of computers the AGI could help those countries that it controls to overpower the others over the long run.
I think he meant more along the lines of computers/robots/ non-super AIs becoming more powerful, IDK.
In a recent essay, Brian Tomasik argues that meme-spreading has higher expected utility than x-risk reduction. His analysis assumes a classical utilitarian ethic, but it may be generalizable to other value systems. Here's the summary:
