According to the Bible, God created man and woman in His image. From the Unification perspective, this is related to the "principle of resemblance": a created being has at least some of the attributes of its Creator. As a result, the Creator experiences joy by relating to the created being. This principle of resemblance extends to human creativity as well. We like to create things that resemble us, in terms of appearance or functions or both. This is clearly the case in the construction of robots, especially humanoid ones.
The question then becomes, will we ever succeed in creating robots that have their own intellect, emotions, and volition? Will these robots be capable of self-awareness, will they be driven by independent thoughts and feelings, and will they create new inventions on their own? According to the Unification viewpoint, these attributes and abilities are connected to the human spiritual dimension that is endowed by God. As long as robots are machines without a spiritual dimension, their internal and external capabilities will be no more than simulations of human mental and physical abilities.
We can indeed build machines that excel in certain tasks and perform them better than we can, but the machine remains a device with its own mechanical limitations. Some robots may be given a limited degree of "intelligence" and decision-making ability, provided by the technology of artificial intelligence. Such robots include feedback loops so that they can interact with and respond to their environment. They do not, however, display the range of mental and physical capabilities that humans do. Most especially, "decision making" in robots can never be grounded in the uniquely human, God-given trait known as "responsibility." Responsibility is the foundation of freedom of expression and the ground upon which the "Three Great Blessings" are to be realized by each and every human life.
Research into robotics has revealed important differences between humans and machines. One important lesson we can learn, therefore, is that human beings are not machines and should not be treated as such. The abilities, activities, and value of humans will remain distinct from and transcend those of any machine.
