“The human body is a very complicated interrelated system and decline due with age consists of multiple interrelated changes. Solving any one of them can be expected to add at most a few years to life expectancy, to add a century or centuries may require us to solve all or at least most. In principle it should be doable, since the information to reconstruct my body is in every cell, massively redundant; if the information in one cell is degraded by mutation it can be reconstructed by majority vote of several others. In practice … Suppose we do it. What would the world be like? I am certainly in favor of my being able to live for centuries but it is less clear whether I should be in favor of everyone being able to do so.” (01/21/25)
