Long-term, if we allow AI to manufacture machines, the set of such things is empty.
Immediate-term, it's pretty clear that natural division of labor is that computers do the thinking, and humans do the menial, manual work that requires mixing precision and power movements in field conditions.
Ironically the person verifying the output does both the thinking and doing in that regard. For without this - the output of an llm could be of zero value.
We change as a society the definition of intelligence to "what humans can do better than AI".
We end up in a world where AI is only worse than humans in things where we are worse chimpanzees.
