Nothing anthropomorphic about it. Whenever a superior species emerges, it exterminates all direct competition in self defense, leaving only those organisms that do not compete directly.
Humans, however, have been especially good at it. Because evolution itself evolves. It’s unlikely the robots will be less efficient.
Humans exterminated the sabretooth and domesticated the wolf. When we no longer needed dogs, we bred them into absurd forms for our own idle amusement. These are the two possibilities. If we have descendants, they will be two-legged shi-tzus and weiner dogs.
