I think humanoid robots are attractive to techbros precisely because they allow them to further disrespect people, to make laborers work without rest, to give no consideration to their wellness and aspirations, and yes, to literally fuck them whenever they so desire. In other words, to conjure up a race of servants, mechanical or otherwise.
We already live among robots. But with humanoid robots, techbros want us to live among a race of slaves, only some of whom are mechanical.
