Robots are something that often reminds us of sci-fi movies where robots are usually portrayed as evil and are often trying to destroy humanity. I do not think that this will happen as robots do not have free will. On the other hand, they might be able to partially imitate human behavior. This ability could potentially make them good companions if they were programmed properly. There are already robots being made that spend time with children. Although they do not speak a lot, children often treat them as living beings. There is some potential for robots becoming our companions, and while they will never replace humans, they could become alternatives to pets such as cats or even dogs. Are you ready to replace your cat? Probably not, but maybe in the future people will.
