So I'm going to do something unusual. My usual habit with stuff I find interesting is to post it wholesale to silk, both for myself to find later and for the minds here to process and comment on. Here' I'm posting only the latter half of some speculation by Charles Stross, a more-than-usually-insightful one ( a large claim) - and a fascinating take on a not-uncommon SF trope.
I recommend you read the entire thing. And I am eager for your thoughts on this. Udhay http://www.antipope.org/charlie/blog-static/2014/11/symptoms-of-ageing.html Let us suppose that in the next couple of decades we develop a cure for the worst problems associated with senescence. We figure out how to reverse the cumulative damage to mitochondrial DNA, to reset the telomere end caps of stem cells without issuing carte blanche to every hopeful cancer in our bodies, to unravel the cumulative damage of prion proteins, to tame the cumulative inflammation that causes atherosclerosis, to fix the underlying mechanism behind metabolic syndrome (the cause of hypertension and type II diabetes). We now have a generation of 70 year olds who in 20 years time will be physiologically in their 40s, not their 90s. At worst, they're no longer in the steep decline of late old age: at best, they're ageing backwards to their first flush of adult fitness. You're one of them. You're 25-60 years old now. You're going to be 55-90 years old by then. Unlike today's senior citizens, you don't ache whenever you get out of bed, you're physically fit, you don't have cancer or heart disease or diabetes or Alzheimer's, you aren't deaf or blind or suffering from anosmia or peripheral neuropathy or other sensory impairments, and you're physically able to enjoy your sex life. Big win all round. But your cognitive functioning is burdened by decades of memories to integrate, canalized by prior experiences, dominated by the complexity of long-term planning at the expense of real-time responsiveness. Every time you look around you are struck by intricate, esoteric cross-references to that which has gone before. Every politician, celebrity, actor, blogger, pop star, author ... you've seen someone like them previously, you know what they're going to say before they open their mouth. Every new policy or strategy has failure modes you recognize: "that won't work" is your usual response to change, not because you're a curmudgeonly pessimist but because you've been there before. Maybe you're going to make extensive use of lifeloggers or external prosthetic memory assistance devices—think of your own personal google, refreshing your memory whenever you ask the right question—or maybe you're going to float forward in time through a haze of forgetting, deliberately shedding old context to make room for fresh. Some folks try for rolling amnesia with a 40-70 year horizon behind them. You gradually lose contact with such people because they just don't want to know you any more. Others try to hang on to every experience, wallowing in the lush, intricate texture of an extended lifespan until their ability to respond is so impaired that they appear catatonic. Which are you going to be? And how will you cope with a century of memories contained in the undecaying flesh of indefinitely protracted adulthood? -- ((Udhay Shankar N)) ((udhay @ pobox.com)) ((www.digeratus.com))
