Robots: Cool or Creepy?

In the class, we talked about robots and how human like they can be in the present and what they could be in the future. It may seem that all of this is just science-fiction but we as the human race are very close to having robots being a part of our lives in the near-future. To me, all of this seems great but then we started to talk about the uncanny valley and how our fondness of human-like robots become unsettling and creepy as it becomes more and more like us. I would have assumed that we like the look of the human race and how we appear so I thought that our fond of human-like robots would go up. I was surprised by this valley. Why do we like robots that look like us to a point then goes down to being creepy?
In the class that we talked about this topic, we watched a filmed called "The Black Mirror". In that film it touches on how we are close to having robots that could be like us and do everything that we can do. The main character, Martha, has to deal with the death of her lover, Ash, and the way she does it was to get an android with the appearance of her late lover. The android looks and sounds like him but they were based on just things found on the internet that he posted or shared. I found this really fascinating. Before, she was fine talking to him through the phone that had the sound of his voice but when it came to the looks and the behavior, it just seemed creepy. Martha was never really satisfied with the android because it just didn't act or feel like he was really there. It came to the point where she wanted it to fall off the cliff but when she told it to act afraid like how the real Ash would have, she couldn't bring herself to see him die. I thought that was an almost cruel fate to her. She could not move on from him. She is almost trapped with it and at the end, her daughter is having a sort of friend relationship with it. Some people may say that the android was human, but I believe it is just a husk of what the real Ash left behind. It could not really act on its own. It was really basing every action on what the real Ash would say and do and not even that was perfect of what the real Ash would do. Even when it was afraid to jump off the cliff, it was only acting to be afraid and based that on what the real Ash would act in that situation. It was as if it was an impersonator trying to be something that he isn't. I believe that it is just an object created by humans and that is trying to be what it was programmed to be. That could also be a factor that can cause us to think that what we think of human-like robots being creepy.
