Bootstrapping to an Ageless Future
Edge excerpts Ending Aging: "An important fact is that the therapies we develop in a decade or so in mice, and those that may come only a decade or two later for humans, will not be perfect. Other things being equal, there will be a residual accumulation of damage within our bodies, however frequently and thoroughly we apply these therapies, and we will eventually experience age-related decline and death just as now, only at a greater age. Probably not all that much greater either - probably only 30-50 years older than today. But other things won't be equal, and I'm going to explain why not - and why, as you may already know from other sources, I expect many people alive today to live to 1000 years of age and to avoid age-related health problems even at that age." It's a good explanation of the plausibility of actuarial escape velocity - the step by step process by which we could bootstrap our way to agelessness, one rejuvenation therapy at a time.
