One of the philosophical quandaries of my youth was the question of whether eternal life (on this earth) was actually desirable. A cult movie from the mid 1980s (Highlander) considered this question (well sort of).
While few of us have death wishes, the thought of living forever can cause some queasiness. I suspect this is due to how they consider the question.
It will likely come on the installment plan
Most people consider the prospect of eternal life as something offered right now as a one-shot deal. Eternal, or massively extended life span, will happen by smaller extensions or postponing of the various debilitating elements of aging or illness. You may feel uneasy when considering living forever, but will probably never refuse another five years. I suspect that this gradual postponement (forever on the never-never) is how some may live forever.
You will not be alone
When considering living forever many assume they will be like the character in Highlander. They assume that they will forever watch those they care about grow old and die. In the movie, only the hero (and a few other immortals) could live forever. If medical and scientific advance does offer us eternal (or greatly extended) life, it will offer it to most of us. It will not be a case of a few immortals watching their loved ones grow old and die; it will be a case of not growing old together. It will not just be extra years for yourself, but extra years for your friends and loved ones.
So, Who wants to live forever
I am not entirely convinced on the likelihood of a transhuman/singularity future. However, I cannot see anyone turning down the chance at a “few more years.” I am not even sure it is a good thing for us all to live forever. Of course, I do not worry about me, or my loved ones; it is all those other people clogging up the earth by living forever that worry me.
I still have not answered the youthful philosophical question of living forever, have you? Would you want to live forever? How would the world cope with an ever growing population (no, or few, deaths to balance out even falling birth rates). Would anyone have children if they already had achieved immortality by not dying? What would a world of increasingly old (even if very healthy) persons look like? Is the prospect of death an important part of living?
I know, too many questions for a Monday, but at least it offers a break from “Cyber Monday” bargain hunting.
