Like you said, the key is empathy. For now, humans are the best at this. By having empathy, we give each other a sense of existence. This is what every interactions and business transactions are about!!! My home smells like wet socks. There is a sales person who empathize my problem at QSquare to introduce Lavender scent candle to me. We will all still have things to do because people are social and need each other.
Regarding IQ, it is more about surviving in the world. There are many 30 year old man with severe down syndrome who can bearly express himself. Let's hope the advance in technology can really help him increase his IQ to a level where he can sustain himself. The best is that he also gains empathy and is able to help others so that others depend on him. This way he is in the virtuous cycle of give-receive-give that forms our society.
Repetitive jobs are spirit killing anyways.
