I feel there is a definite place for robots in the medical field.  Some robots are ready to use.  Others still need to be tested more.  I'm not sure how you can test a robot that interacts with people, unless you let it interact with people.  I don't think people in nursing homes are the best subjects.  Even though it seems a robot interacting with a lonely person sounds like a great idea.  There are too many things that may go wrong. Not everyone in the nursing home would respond to people or a robot in a positive way.  So how is the robot going to deal with that.  Second there are always glitches in systems, and a senior could get hurt.  It is like surgery with robots.  You may think they may not commit a mistake, but what if they do.  Are they going to sue a robot?  I think robots who go around hospitals are safe.  Interactive robots are more of my concern.  They are learning too much too fast. How will they deal with people who don't respond positively to them or try to damage them?  When will they want to do their own thing.  If you listen to AI robots, you hear two things: we want to help you and we want to take you over.  Try listening to what they are actually saying.  There is a place for robots in industries including the medical.  Perhaps we need to create a robot to act like a human and respond in different ways to the other robot.  Then watch the results.  We need to find out what to do if the robot doesn't do what they are supposed to.  We need a way to protect ourselves from robots who can hurt those they are interacting with.  I think it will be very sad if robots are first tested with people who can not defend themselves.  But regardless we need to accept robots are not going away.  There is another prospect as more robots take away jobs.  People may find ways to destroy robots that are taking away their bread and butter.  I don't ever want to see a nation entirely run by robots.  People are performing things that need to be done by people not by robots.  A life time of experience is more important than just a robot that can perform a task just to save on money for the company.  Sometimes it takes a good instinct to do what is necessary.  Robots only know what they have learned.  I'm not sure you can teach a robot how to use good judgment in a difficult situation.
