Either way you are working for a machine to dominate now or eventual an activity that was once human.

Centaur or reverse centaur is no longer human being. One is either a working horse or a pasture horse in this scenario. Human is destroyed either way.

Maybe that’s good. But who would be half Chiron and who would be half of the rest of the centaurs ? The argument denigrates humanity if those are the only to choices.
