Humans can be paid off , bribed , and have their own agendas , much less trustworthy than a machine <| sep |> Sweet ! If you like , you can join us over on the Discord channel .

The concept of marrying someone and procreating with them because it serves a benefit for their familystatus rather than they just found them attractive is a pretty old concept . Obviously this would be more impactful for some cultures than others , especially depending on how procreation was limited like a concubine situation compared to a multiple wives situation compared to two people being completely monogamous . But even in such a relative short time , this can make an impact .
