If humans are machines, they are still a subset of machines and they (among other animals) are the only ones who can be demotivated and so it is still a mistake to assume an entirely different kind of machine would have those properties.
>Other living-person-machines treat "you" differently than other clusters of atoms only because evolution has taught us that doing so is a mutually beneficial social convention
Evolution doesn't "teach" anything. It's just an emergent property of the fact that life reproduces (and sometimes doesn't). If you're going to have this radically reductionist view of humanity, you can't also treat evolution as having any kind of agency.
