in the westworld all androids are created by the owners & their staffs, their purpose are to earn money from the human visitors by offering them androids entertainment ; only androids can gun androids & their guns cannot hurt human therefore ed harris is a human if otherwise

at this point, all androids are manufactured, no real human turned to androids

Dolores is the oldest androids reprogrammed repeatedly just like her father Abernathy ; Abernathy told Dolores the Shakespeare Quotes meaning they were being exploited by their creators & the visitors' pleasures over & over again, he felt sad he couldn't do anything - he was in fact relaying his feeling to Dolores who seemed unable to comprehend, but end of scene showed she swatted off the fly on her neck implying she mildly felt disturbs ; it could be the androids beginning to show defects even the reprogrammings couldn't resolve but Dr. Robert Ford & Bernard didn't realize

this series is about androids turned against their creators, when they start to think for themselves out of what they are programmed for
