It's certainly an interesting line of inquiry. Replacement of 100% of human labor would seem to imply a very sophisticated artificial intelligence. We don't yet know what properties that AI would have. Would it be sentient? Would it have ambitions and desires? Are these factors even in our control, or are sentience, ambition, and desire strictly necessary for any AI capable of replacing all human labor? Would there be ethical implications if we put an advanced AI to work? Would the AIs deserve and/or demand full citizenship? Et cetera.
