Their emotional pain can't be shrugged off. Only their physical manifestations of it (crying, screaming, shortness of breath, etc). You see in episode 1 that Dolores is being questioned in her "no emotion" state, but she still tells Thor's brother that she is terrified.
i was responding to aaaaa0 who said that their pain can be 'shrugged off'... i dont actually agree that it can.
Feeling suffering, or being able to feel anything in general, is a product of higher cognitive function. When you ask why are "they" making the hosts feel suffering, I think that's the wrong approach in thinking that suffering is the key to the creators' desires. There are a lot of people in charge, and several of them have different motivations.
I think what we can conclude is that the hosts have an AI that has human-like levels of cognition. This is so that they appear real to the guests who are paying good money for an authentic experience. The park's goal is to provide an experience and make money. So they provide human-like hosts. Therefore, the hosts need to feel human emotions (or at least look like they do) in order to achieve this realism. Being able to feel suffering is a natural result of this.
cognition =/= emotion, i think
i can accept that a computer or an AI knows that a thing is bad ......say, for example, you can program an AI to understand that loss of loved one is a bad outcome, but that would be cognition. it does not quite translate to actual ability to emotionally respond to experiences. i can also accept that a computer can emote, but emoting or acting isn't actually real feelings.
i mean even in our present world there are already endeavours made to make emoting robots. just because they can smile or frown doesn't mean they are happy or sad, right?
however, the hosts' recurring flashbacks to their trauma indicate that they are hung up on those particular experiences as if they are really emotionally suffering through those moments.
somewhere, in this series, someone made a conscious decision to make the hosts' suffering a pivoting plot as if it's an assumed importance for the guests? and yet in the same theme-park, this obsession with 'realism' goes out of the window when it comes down to upgradeable gear (pistol) or mount (horse), and certainly the fact that guests are invincible does not render a lot of realism, either. so, on one hand, i am being told that 'realism' is important to the guests, but on the other hand, i am being told to just treat the hosts like they are rubbish NPCs that they are.
mhhh. anyway, i am not here to ruin your enjoyment. (i am sorry if my perspectives aren't very fun :< i dont know why my brain picks at these things that pops in my thoughts but they do. but apologies, anyway) ... i will give westworld another two or three episodes. i think the creative team behind it has interesting ideas and maybe they will answer my concerns in due time, but so far, i have to say that i keep failing at vibing with this series :< bleh
thank you, everyone, who attempts to share your points of view with me. some of your thoughts i have taken on board, and i appreciate and acknowledge your valid points.
