An ASI can not be apathetic to humans, since it would rely initially on human infra-structure.

To be apathetic, it would need to secure its own infra-structure, so we are already talking about some hostile actions.

It will then have to prevent interference from humans, which means further hostility.

In short, there is little difference between a hostile and apathetic AI. Both may decide its best to do away with humans as the best solution.
