The generalization of the self-concept to the superself is unlikely to receive a reception much different from that accorded Twain's What Is Man?.
The co-creation characteristic of the superself will be scorned as collectivism, if not socialism. Reciprocal dignity will be ridiculed as utopian. Asking "What am I?" instead of "Who am I?" will be dismissed as reductive, mechanistic, and heartless.
Although the superself incorporates the witness, and so has a religious provenance, it's fair to ask if it will ever speak to the heart as traditional religious models have done. It's not easy coming to terms with life as a property of inanimate matter, arranged just so, and it will likely be even more difficult to accept ourselves as extended, self-conscious, willful machines.
Many will feel that this outlook is arid and bleak, and want to know: Where's the mystery? How about love? Doesn't this mean that free will is an illusion? Awe and wonder and the occasional "Eureka!" may be enough for science, but religious models have offered fellowship, absolution, forgiveness, salvation, and enlightenment. People of faith will want to know what's holy in this brave new world.
The perspectives of religion and science on selfhood, though different, are not incompatible. Without oversimplifying or mystifying either, it's possible to identify common ground, and, going forward, a role for both traditions. I propose such a collaboration in Religion and Science: A Beautiful Friendship?.
My guess is that once we're in the presence of machines that can do what we do the model of selfhood we'll settle on will be even more fecund than the traditional one. That co-agency replaces individual volition will not undermine a sense of purpose, though it will require aredefinition of personal responsibility. There's no reason to think that machines that are sophisticated enough to outperform us will evoke less wonder and reverence than organisms that have arisen via natural selection. Mystery does not attach itself exclusively to human beings. Rather, it inheres in the non-human as well as the human, in the inanimate as well as the animate. As Rabbi Abraham Heschel notes, "Awe is an intuition of the dignity of all things, a realization that things not only are what they are but also stand, however remotely, for something supreme."
Contrary to our fears, the capacity of superselves for love, fellowship, and agency will be enlarged not diminished. As the concept of superself displaces that of individual selfhood, the brotherhood of man and its operating principle--equal dignity for all--become self-evident and self-enforcing. Nothing in this perspective bars belief in a Deity for those so inclined. Having said that, it's implicit in this way of beholding selfhood that if there were a God, He'd want us to behave as if there weren't. Like any good parent, He'd want to see us wean ourselves and grow up.
The superself, with its inherent co-creation and co-agency, not only transforms our relationships with each other, it also provides a new perspective on death. As mentioned, it's arguable whether selves survive the death of the bodies in which they're encoded. But, survivability is much less problematic for superselves. Why? Because they are dispersed and so, like the Internet that was designed to survive nuclear war, provide a more redundant and robust defense against extinction. As William Blake noted three centuries ago:
The generations of men run on in the tide of Time,
But leave their destin'd lineaments permanent for ever and ever.
In the same sense that the soul is deemed to survive the death of the individual, the wenome survives the disintegration of the body and the mind. The absence of a particular individual, as defined by a unique genome and menome, puts hardly a dent in the wenome. The building blocks of superselfhood can be thought of as genes, memes, and wemes. All three encodings are subject to evolutionary pressure.
Although some may feel this reformulation of selfhood asks them to give up the store, it will gradually become apparent that it's only the storefront that requires a do-over. To give up standalone selfhood in exchange for a open-ended leadership role in cosmic evolution is a trade-off that many will find attractive.
As Norbert Wiener, the Father of Cybernetics, wrote in 1949:
We can be humble and live a good life with the
aid of machines, or we can be arrogant and die.
