In cyberspace, the range of self broadens and becomes more diffuse, sliding up and down the scale between lesser selves and the greater Self as it is gradually liberated from the body. The question is whether this diffusion threatens the environment of human properties. And, of course, whether the greater Self becomes greater. I don't think so. We should take a look at evolution to inform our thinking here.
Life forgets nothing, discards little.
At the base of our genetic code is blue-green slime genetic code. We ascend upon depositions of layered complexity through cellular collectivization into vertebrate forms and finally into the anxious, itching consciousness which now appears compelled to create new, overarching forms of a more global consciousness to layer above itself. Just as the blue-green slime code remains intact at its rudimentary level in the Great Chain of Being, so the old properties as manifested by individual humans will probably survive, largely unmolested, their incorporation into the new whole mind now being born above them, Humanity Itself. I think of the self, as we understand it, like mitochondria. Mitochondria are freestanding creatures from the primordial goo that gradually became enveloped into the physical structure of multicelled animals.
