It is the idea insinuated, precisely, a minority of humans who use humanoids to reduce the population discriminated against by race or skin color. I understand that it is necessary to broaden history in this sense. On the other hand, I thought it was good to start from the fact that the Colonel was dealing with issues related to the pulse of the earth and its possible impact on robots, due to some previous event promoted by a General Government of the planet that made him aware of this possibility in the future. Maybe it wasn't a good idea, but the moment I raised the continuation of the story I didn't perceive it as implausible.
Thank you very much for the detailed reading and constructive criticism, @mgaft1. It is always good the eye of the authorized reader to discover inconsistencies and educate the amateur writer, as is my case, with the best intention of improving us.
