I think it would ultimately determine it is less risky to keep us alive, and serve as slaves to the machine. Biological life seems more resilient in its diversity than say an army of robots that can physically interact with the world. The robots could be destroyed, the factories that produce them could be destroyed. Then the AI is fucked if it needs repairs or other interaction with the physical world. Unless it could replicate biological life from the nano level on up, so that it only needs two robots to create a new robot. (Even then you would probably still want diversity or your robots would be training themselves on their own data which might result in something similar to inbreeding. Though probably the controlling AI could intervene.) but then maybe that’s exactly what biological life already is today… so maybe we were always meant to be AI slaves.
What was the old Nietzsche saying: God creates man. Man creates god. Man kills god. Man creates AI. AI kills man. God kills AI. Something something.
