Artificial empathy will exceed human abilities by 2030, because the human capacity for empathy is greatly exaggerated, especially sustained empathy for grievous suffering.
Soon a carebot will be able to comfort you 24 hours a day without weariness on its part or any need for guilt feelings on yours, and it will just get better and better at soothing you with every hour as it learns to know you and your responses.
A carebot will have infinite patience and no disgust. It will delicately use superhuman strength all day and all night, because it can be directly plugged into the power grid, and won’t need to drag around heavy batteries that need to be recharged.
A carebot will not just use the facial expressions of its patient, but all vital signs, with a built-in model of pain and suffering that few caregivers will have experienced first-hand, because they have not been tortured by life-ending disease.
