To carry this argument further, it needs to be said, that given the point of view, that either courses may be taken, or neither, or both-simulteniously, in concert to benefit those men, machines, men-machines, who seem to be the so called elite social control of society. In that case, it would matter little which from would be most applicable to maximum capital, service and utilization. We cannot automatically assume, that pure machines would be the most profitable in that respect, and that is why i feel that issue is of yet indeterminate.
Given the fact, that Nature Herself can overcome a non controlled ,limitless growth of population without consequence, control of populations can already be seen for instance, in the social manipulation of normative morals, as exemplified by changing moral behavior. Is this the work of man, or nature is a mute subject, since man is an extension of Nature. In which case, even robots and cyborgs are natural, the only requisite value to that eventuality, is that artificial programs and minds stay close to the intent, form, and content of the programmer. The result would effect an eternal consciousness.
It is quite possible, that our present ‘re-awakening’ into the realms of the de-differentiation of the brain with mind, may in the near future lead to greater discoveries, and in the far term, offer insight into such previously sacro sanct concepts such as reincarnation, personal information storage, and time/space travel backwards and forwards. I think it is conceivable, if machines would become almost having total control, that personal self consciousness may be keyed into ephemeral machines, capable to keep that going fairly indefinitely,at least, until the spaceship transporting such entities stop finding host planets. Perhaps that too, can be overcome.
Given that type of scenario, machines may resemble a Wellsian world, and it may really become a very involved and highly competitive life work for those, who still want to continue.
This is why i think religion is so very important, the personal ego once tamed, death will not seem as threatening, and god will be interpreted as the keeper of souls, in a mass-think thank, with minimum individuality. It takes a lot of faith, to be able to join a group-think, and the venture capitalists, who may attain immortality, will gradually be reduced numerically. Two empires, one good, the other bad, may learn to coexist with periodic conflicts and resolutions thereof.
At this point, the major cataclysm, will force natural process to cast down, the eternal ones.
Here, a new incarnation will begin, a brand new beginning, the evolutionary steps imperceptibly , but virtually, land a new man, into a brand new world,within a clear slate.
So the answer is yes, there will be an age of cyborg gods and human underlings, but not long enough for man to remember the very long sleep between incarnations, and for them, god, satan will again will become an existential necessity. So the answer is also no. This is why i stay within the indeterminable column. You, never really know, will never know, because even in that age, blade runners, and humanoids will subsist, even as, there was some modicum of self recognition in the laboratory of Dr. Moreau.
