However these facilities have been designed to last just 40 odd years, just enough to produce and look after a child. After this time the self repairing mechanism slowly goes to pieces, leaving the human to perish in agony. The proposed new beings would find perfect fulfilment in helping humans. Humans usually fail to find fulfilment in producing children. The new beings would also be physically immortal, and by a process of recording could be invulnerable to death by accident.
Humans die of old age and accident, often in pain and distress.
Also, it could be possible to have the automatic processes of the body switchable to control by the higher level of intelligence to deal with injury and illness. Rather than suffer in pain after injury, the proposed being could choose to dump program and data into a store and then shut down. Then a human could make a new body for the android and play the program and data into it. If it was damaged so much that such action was not possible, then the most recently recorded program and data could be used in the replacement. It will not be unethical to make them.
