SAGE Crossroads outlines the "Methodical March to Immortality," a good summary of the polar opposite of SENS in gerontology. Where Aubrey de Grey makes a good case that we know more than enough to begin the war on aging now, the methodical march crew want to move slowly, completely, genome by genome, five year project by five year project. The first, "funded by the Ellison Medical Foundation, [will] begin by scouring the entire yeast genome for genes that regulate longevity. The researchers will then take these life-extending genes and search for their counterparts in worms and mice." There is a time and place for completeness in science, but it isn't fast - and we need rapid development if we are to avoid the age-related disease, degeneration and suffering that has befallen every human to date.
