It seems likely that the next century will see the engineering of new humans to have genetic alterations that have been identified as wholly beneficial. It is a lot easier to edit the genomes in an embryo than it is to adjust all of the cells in an adult in the same way, due to the issues of delivery of suitable genetic medicine to all cells in all tissues. One interesting class of beneficial gene variants are those associated with what is known as natural short sleep, a phenomenon in which a rare few human lineages need very little sleep, as little as a few hours a night. More time spent awake in a lifetime is somewhat analogous to living for longer. So far ADRB1 variants and <a href="https://www.fightaging.org/archives/2…
