  It seems to me that we humans are trying to divorce ourselves from the other animals on the planet as much as possible.&nbsp; We buy our food in supermarkets and cook it, we sleep in well built houses on beds.&nbsp; We speak to each other and wear clothes. &nbsp; However, it seems to me that we are still linked to the animal kingdom, because we shit.&nbsp; It is a distinctly animal trait to just wander off to a corner somewhere, squat and curl one down.&nbsp; It produces no useful output, it's waste we have to deal with, and it's a waste of our time too, so my question is this: &nbsp; Do you think a time will come when technology advances enough that humans don't shit anymore?
