If AI gets really good, manual labor automation won’t be far behind, as the AI itself will be applied to robotics and AI research.
The only thing of value left will be natural resources.
Sounds like good motivation for the machines to kill us off and keep the resources for themselves
That’s assuming they have that goal. The goal of survival and reproduction exists because of natural selection (those that don’t have that goal simply don’t make it into the next generation, when competing against those that do).
But that doesn’t necessarily apply to AI systems. At least while humans have a say in which systems survive and get developed further, and which ones get scrapped. When humans control the resources, the best way to get a sizable allocation of them is by being useful to humans (or at least making them believe that).
