Robot can be used in our life, but not as a friend.
It is often seen in movies that the robots become to have feeling or heart as human. I do not believe it comes to true. It is mere a human-made product, so it is not perfect.
About Saya, she looks really scary. Children will cry if she is in the house when they go to bathroom in the midnight. We can have affair to the robot as a thing but not our friend.
It should be clearly separated and we should not depend on it too much because they cannot recognize the danger that can only be sensed by eye, nose, and ear.
