Why did the humans create replicant's so they cannot be told apart?
Basically the replicants are suppose to be slaves and low level workers, working for the humans, doing mostly manual labor type jobs it seems, right?
But if this was the case, then why did the humans create them so they needed to be asked questions in order to tell them apart? It seems to me that the only reason to make a replicant to look just like a human on the inside as well as the outside, is if you are sending the replicant to do a spy mission, where you needed to fool an enemy.
But not for manual labor jobs, where passing as a human in full physical form doesn't matter. What do you think?
