Why watching Westworld's robots should make us question ourselves

For a sci-fi fan like me, fascinated by the nature of human intelligence and the possibility of building life-like robots, it's always interesting to find a new angle on these questions. As a re-imagining of the original 1970s science fiction film set in a cowboy-themed, hyper-real adult theme park populated by robots that look and act like people, Westworld does not disappoint. Westworld challenges us to consider the difference between being human and being a robot. From the beginning of this new serialisation on HBO we are confronted with scenes of graphic human-on-robot violence. But the robots in Westworld have more than just human-like physical bodies, they display emotion including extreme pain, they see and recognise each other's suffering, they bleed and even die.
