what would be the hardest human feature to emulate in a robot?

Emotions in robots have always been a problem and have been illustrated in films and books such as AI and I-robot. It would be easy to program a robot to behave in particular situations mimicking human response but a robot would never actually be able to FEEL the emotion. Will robots ever be able to have an imagination? They can think things through and solve problems to chose the best options, but would a robot ever be able to think of a new idea in the same way humans are able to write fictitious novels.

All are surprisingly interdependent on different existence varieties: The human might possibly stay a short existence with little objective. The Hologram and robotic might have certainly no objective with out people and can choose a greater robust capability to recharge itself, and for what?; The mutated cat would possibly not have the skill to reproduce, yet you probably did not point out that it grew to become into the "final" mutated cat, so it ought to stay a lifetime of being a misfit between the different cats.

I don't think any currently living person will see an AI capable of having a conversation about an abstract topic to the same level that a human can.

3 things i guess emotions and reproduction

and soul

the brain

emotion.

Altruism, hope , regret.........the list goes on..................
