It’s not about physical love. Every day people use more and more technology in their lives which makes them look like robots described in science fiction. You can see such cyborgs of 21st century on the subway playing with their iPhones or staring into space while listening their music. As for artificial limbs, organs and eyes? Already a reality.
Furthermore, robots have become more sophisticated. They can walk, talk and learn. Man and robot have become more alike and at some moment the difference will disappear. When this will happen – the problem will disappear. Sooner or later we will stop worrying about that, and that will be normal. So meet you on the other side!
