Social robots for long-term engagement
Humans are, generally, adept at interpreting social behavior. Robots are not. The study says the three biggest challenges of building social robots that truly interact with humans are modeling social dynamics, learning social and moral norms, and building a robotic theory of mind
Today’s social robots have been designed for short interactions, which isn’t how human relationships work. Social robots must expand from moment-to-moment engagements to long-term relationships.
I agree because its not like robots can express their thoughts when it comes to giving personal opinions. Even now also they haven't advanced till that level where they can understand the problems of a person by watching their body language and facial language which is a must while interacting with someone socially. If they want to interact with human or any other outside agent, they must be well aware of how to hold conversations and learn quite a lot about social standings, its not an impossible task but if they get to focus more on communicating and learning more about human beings, then they'll have no problem holding interactions and form relationships with anyone.
