How advanced were robots that many decades ago? The episode was about a family. Dad, mom and daughter. They had a maid. At one point daughter dearest started getting hard to handle..insistent. They always stayed in that house and she wanted to go out into the world. The last scene shows the robot that was "the daughter" is now the maid. The robot that was "the maid" is now the daughter. Makes me wonder if the father had a robot wife as well. The robots in that long-ago TV show didn't know they were machines. They looked human. Could we all be robots and not know it?
