This is a cruel reality.
Life-extending technology could not possibly benefit everyone. "Old people" are incapable of surviving the "species renewal" process.
To ensure the smooth implementation of technological applications, the first group of recipients of the Benchmark Man's gene modification surgery would only be vigorous young adults. Those who are nearly at the "ineligible for surgery" age are also essentially abandoned.
For some middle-aged people on the cusp, "a few years" is terrifying. Perhaps because of an illness or something else, they would become "old people."
Superman Enterprise developed gene medical technology that can eliminate diseases and fend off aging.
But it cannot benefit everyone.
There will always be those who are left out of this historic moment.
And these people might have dedicated their lives to the functioning of human society as elderly individuals.
