“Imagine A World In Which Ageing Had Been Abolished”

I don’t want to die, but have I any other options?

Anti-aging therapies are genuinely advancing, but I don’t suspect they’ll be ready for those of us who’ve already reached adulthood. But what of those being born now, those to come into the world in 2050 or 2100? How long a lifespan will they enjoy? When will life become radically extended and 120 a routine age? Most importantly: Will aging ultimately be cured?

Lifespans grew much longer over the last century or so because infant deaths were markedly decreased, medical procedures became far more sanitary and antibiotics were discovered. It was elongation born of improvements at the margins. The next wave will attempt to go to the heart of senescence, to treat it and defeat it, with gene therapies, an endless supply of replacement organs and other measures.

It will be great but complicated. In “Cheating Death,” an excellent Economist piece that asks us to “imagine a world in which ageing had been abolished,” the writer identifies some of the clouds in an endless summer, from income inequality making access to treatments wildly uneven to severe strains on pensions when people are routinely centenarians or perhaps far older. It’s a really interesting thought experiment, though I think it falls into the trap of extrapolating one key thing (life extension) while keeping all other factors (economics, etc.) static. Life rarely proceeds in such a manner.

An excerpt:

From an individual’s viewpoint, this all sounds very desirable. For society as a whole, though, it will have profound effects. Most of them will be good, but not all.

One concern is that long life will exacerbate existing social and economic problems. The most immediate challenge will be access to anti-senescence treatment. If longer life is expensive, who gets it first? Already, income is one of the best predictors of lifespan. Widening the gap with treatments inaccessible to the poor might deepen divisions that are already straining democracies.

Will older workers be discriminated against, as now, or will numbers give them the whip hand over the young? Will bosses cling on, stymying the careers of their underlings, or will they grow bored, quit and do something else entirely? And would all those old people cease to consider themselves elderly, retaining youthfully vigorous mental attitudes as well as physical ones—or instead make society more conservative (because old people tend to be)?

A reason for hoping that the elderly would turn out less hidebound is that life itself would be more a series of new beginnings than one single story. Mid-life crises might be not so much about recapturing lost youth as wondering how to make the most of the next half-century.

Retirement would become a more distant option for most, since pension pots would have to be enormous to support their extended lifespans. 

To this end, the portfolio career would become the rule and education would have to change accordingly. People might go back to school in their 50s to learn how to do something completely different. The physical labourer would surely need a rest. The accountant might become a doctor. The lawyer, a charity worker. Perhaps some will take long breaks between careers and party wildly, in the knowledge that medicine can offer them running repairs.

Boredom, and the need for variety, would alter family life, too.
