Souls
I think techfolk would probably not be religious because they've met their creators. What might happen several generations after humans are extinct? Might some young techfolk doubt the existence of humans?
I remember reading a short story1 about robots, in which young robots refused to believe their kind had been created by humans. Robots are clearly superior to humans in every way, so how could an inferior being have produced them?
Perhaps robots would argue that they have souls and humans don't. Robots are cartesian dualists with separable bodies and minds. The mind can be transferred to another vessel, thus is effectively a soul. A human mind, on the other hand, is inextricably linked to the meat in which it resides.
I feel my readers would appreciate knowing that in this story, robots orgasmed when they 'reproduced'. They had some sort of crystal inside them and they had to make the crystal resonate or something in order to spin off a new mind (to put in a new robot body). The crystal resonating put them in a state comparable to orgasm in a human. I cannot remember the author or title. I just remember it being in an old paperback that was a collection of short stories.↩
