After talking about Death, it seemed natural to next discuss Immortality.
Not to debate the afterlife of religion, but rather to speculate on the impact of immortality (or at least, massively extended lifespan) on our temporal world. This may seem fanciful, but the aging phenomenon is one of the most fashionable fields of scientific research. Advances in DNA rejuvenation, cloning, cybernetics, neural interfaces and more may advance fast enough to keep pace with illnesses. Less than one year of scientific research may be required to keep our children alive each further year, thus granting them effective eternal life; “actuarial escape velocity”.
My generation could be the last to face death from old age.
If something close to physical immortality is possible, the impact on our societies will be immense. Firstly, to avoid a world of young, fit and healthy bodies with progressively vegetating minds, we will also need similar advances in understanding dementia and the general cognitive decline that accompanies aging. Assuming this can also be mitigated, what will happen to the world if we live forever?
On a prosaic level, personal finances will be transformed. The longer someone lives, the more wealth they tend to accrue. Without death, the next generation will never inherit wealth unless it is freely given during life. The older one is, the more likely they will be to be wealthier, with all the influence and power that large sums of capital offers. Gerontocracy beckons.
But the health care advances that offer such extended lifespans are likely to be very expensive, at least at first. Perhaps immortality will be bought at the cost of hundred-year loans at a time, to pay for the treatment? If so, modern socioeconomic inequalities are likely to be exaggerated and this may lead to significant social unrest. If people riot for religious, political and financial reasons now, how much disruption will they create when the cause is eternal life?
If by some chance these problems are solved, there is still an issue of population. With no death from old age, the population will grow dramatically, straining resources and delivery systems to breaking point. To avoid a drop in quality of life caused by the population growth, euthanasia and curbs on fertility (or forced abortions) may be employed. It may be that eternal life will go hand in hand with many more deliberate deaths. A more pleasant hope may be that longer life might encourage more to seek space elsewhere and colonisation of other worlds would be encouraged.
If the socioeconomic problems of immortality are solved, we would still be left with the more personal ones. What would our lives be like if we lived forever? This is an important thought experiment, for if it reveals an area of life that would be unsatisfactory over the centuries, why should we subject ourselves to it just because we actually live for a much shorter period of time.
For instance, if long life makes indefinite monogamous relationships impossible, either through boredom or simply accumulated irritation over the years, then is it correct to expect such relationships to last now? Already, in a world with life expectancy only in the 80s, it is commonplace for marriages to end and remarriage, perhaps several, to occur.
Similarly, children may become of less importance to immortals. Would we feel as obliged to propagate the human race if we did not need to live through them once we died? And in a world of young immortals, where would we draw the line regarding incest? Great-great-grandmother may look 20, and rather fetching to her 25 year old great-great-grandson. How many generations of separation would be sufficient to maintain the taboo?
Finally, what would we do to keep busy in a world without end? Would the suicide booths of fiction become reality, to cater to the needs of a bored, anomic, populace? Or would we be able to find new interests to keep us motivated?
Immortality is one of mankind’s most cherished dreams. We still have lot of work to do to make it reality, but yet so much more to make it a pleasant one.
