Think of a time in another place, perhaps in another galaxy, but perhaps if we survive as a humanity, when life extension will become a matter of course.
What if, the state of the art of the exchange of body parts, although procedures of extra ordinary cost, would slowly favor those with large pocketbooks, later with inordinately huge ones.
This is predicated on the notion, that all parts could finally be manufactured, and purchased , but the price tag will suddenly escalate dramatically.
If we go to the top of the financial pyramid, like billionaires, they may be able to afford quick replacements, where ‘quick’ may actually expand time longitudinally, as hart valves do nowadays, by the measures of years, stretched to centuries.
Dynasties will survive eternally, and individuals of trillion(s) dollar holdings can perpetuate this scheme.
Whatever cannot be manufactured, may be bought on the black market of human parts, and even now, people are warned of travel to Asia and other places, where a visit to a bar may mean unwary removal of a kidney, after coming to from an ingestion of a Mickey.
If not, harvesting could commence by silent lobotomies, and subsequent genetic growing by cloning.
Where the stronger, smarter , richer, may get to this point, where upon only trillion dollar fortunes may enable this surging quest toward eternal life, only those, whose insatiated thirst for more life becomes unstoppable.
Vampirism of kind where the ever stronger will feed upon those, whose life energy will web, without the lost organs.
Will these super humans acquire the stature of Gods, who simultaneously reduce the humane-ness of men, into creatures to support such an economy?
Is this at all conceivable?
