Proximity of a negligible senescence society

The timeline wherein humanity will achieve a negligible senescence scenario is unclear. For instance, in the

Worldbank projections of demographics until 2050 death rate per 1,000 is increasing year-on-year[4] thus implying no projection of negligible senescence before 2050. Although visionaries like Yuval Noah Harari do mention the possibility of a negligible senescence society Noah also remarks that he seems this is not likely to happen in the 21st century.[5] Only a few people have publicly announced that they deem negligible senescence likely in the 21st century, such as Aubrey de Grey, founder of the SENS Research Foundation

Societal impact

Demographics

The impact of negligible senescence on worldwide demographics is widely accepted;.[6][7] Coale noted that a shift toward near-immortality would have the same long-term impact on population growth as a 10% increase in the fertility rate. As the death rate per thousand people will drop from roughly 10 per thousand (1% per year) to near zero this would thus add an extra 1% population growth each year.[7]

Although aging populations in population pyramids result in "constructive" pyramids which are narrowed at the bottom, this might not necessarily be the case in the aging population in a negligible senescence scenario. Depending on the total fertility rate (TFR) all three different shapes of population pyramids can be observed.[3]

Many questions still remain regarding demographic predictions in negligible senescence scenario's. The TFR has steadily decreased from 5 in 1950–1955 to around 2.5 in 2010–2015. The impact of negligible senescence on future TFR is unclear as there might be a reduced sense of self"replacement". However, this might be offset by no biological limitations on having an unlimited number of children (delay or complete eradication of menopause) which in turn may or may not occur with negligible senescence. Furthermore, the age of mothers might increase or stay stable depending on a myriad of factors thus impacting TFR.[3]

Economics

The impact of negligible senescence on the economy is multi-faceted. Many

developed countries face population ageing due to demographic transition
whereas in the least developed countries people of old age only resembles a small part of the total population. Therefore, the development of negligible senescence therapies have profoundly different effects on the economies of countries with different demographic characteristics. From a worldwide perspective eliminating senescence has a massive effect on the economy. As current productivity losses for employers in the US alone is calculated at 225.8 billion annually[8] the impact can be large. Furthermore, changes in pension plans might enable unlimited perpetual productivity after childhood ceteris paribus and thus eliminating the 'Aged dependency ratio' in the equation of dependency ratios. These effects are partly offset with the costs of providing negligible senescence therapies.[3]

Life in a negligible senescence society

As philosopher Nick Bostrom mentioned in his story "The Fable of the Dragon-Tyrant" referring to the end of senescence: “And in the coming days… I believe we have some reorganization to do!”. Humankind has experienced senescence for all its history. Therefore, major challenges are necessarily to fill the void the lack of senescence has now left behind.[9] However, he does not substantiate this any further into practical measures.
