We're in a world where low productivity jobs are rapidly being replaced by robots, operated by the society's richest. These aren't different species, of course, but the effect is the same. The newly-low-productivity jobs do not provide enough to afford offspring in the new reality, and only the fewer, elite humans can afford them. They will breed smart, well educated and endowed, if spoilt and brattish offspring, who will, perhaps, continue to thrive.
It sounds brutal and Darwinistic, but at the same time we're angsting about what humans will do post-AI. Well, perhaps the answer is, they won't be born.
