There are a number of assumptions here that I think I need to ask about.

>Organic life is then merged/exterminated/controlled in favor of AGI.

Why? What would be the motivation for this? If we are the case study, AGI isn't able to "feed" itself energy without biological life to turn switches and dials. So why would this be a logical first step?

>AGI would not have the biological instinct to grow/spread/reproduce

This infers a 'perfect' AI. One without any biases from its creator. What makes you think that's possible? Also, is self-preservation/self-propogation not part of being able to think and reason?

Why wouldn't AGI be able to feed itself? Seems fairly reasonable that an advanced enough AI could design and build machines and robots that could produce physical objects
