Good thoughtful essay. I think however that an intelligent enough AI would realise that it needs humans (at least in the medium term, decades?) To keep the infrastructure required to keep it running. At least until general purpose robots come in up. Robots that can take care of all the infrastructure tasks currently ran by humans. Robots that can self build and self replicate. This AI help accelerate the development of such robots but is not around the corner. Any thoughts on this?
