Robots are produced to bring convenient for our daily life. In the movie, “Ex Machina”, the robot Ava got his Caleb’s trust to help escape from the lab, and killed Nathan. This movie does a great job of posing questions about the future of humanity and whether we will be able to control AI that may end up usurping us if we are not careful. It’s fascinating to see the robot Ava pretends she is emotionless throughout the film and her ability to use emotions and feelings to manipulate humans is astounding.After watching the movie, I don’t really worry about the future of AI, robots will only have emotions if the one who created it intended to give them and human’s emotion is hard to imitate. It’s true that robots can be harmful to us, due to its error in production. But it’s also true to any other technologies, like automobile, smartphones and headphones. Sometimes, we hear the news of a phone exploding due to its’ bad quality, and it’s just like AI, they could be harmful to us. Therefore, the most important thing is the quality control, we can prevent this happening in the future.
