Yep. It'll just be the same ultra-rich madmen who benefit so they can go on to bleed the people of money, the Earth of resources and all life-except for thiers, of course.
I do wonder about that, like I've wondered if whether an unknown but very definite sort of social stratification hasnt emerged long, long ago already which does not change and nullifies all the progressive gains humanity has otherwise made and is slowly going to dismantle the more obvious ones.
Some of the old fairy tales and stories of magic that I remember as a kid used to have characters who where evil as a consequence of "abnormally long life" and I have thought about that sense, with reference to this topic, there's also this story I remember called The Hunger which is a non-traditional sort of vampire story, the "patient zero" of the vampire plague IS a vampire, eternally young type, but anyone she has bitten is doomed to a kind of immortality combined with decrepitude and eventually becoming pseudo-mummies in their attic space.
Like longevity isnt eternal youth, even in some of wilder predictions from years ago (the best I read lately was The People Shapers, it was by the guy who wrote The Hidden Persuaders, it reads like a work of wild exaggeration futurology but at the time it was pretty much commonly accepted opinion) like head transplants and interchangeable bodies grown in tanks, they havent found any ways yet to stop brain cell death.
Aging will get you one way or another.
Part of why I think longevity is important to most people is that they hope in time their prospects will improve and they could get the sort of lifestyle enjoyed presently by the few and fewer, sometimes that's not even that exuberant or affluent a lifestyle (like the people who're that stressed they dream of just sitting at home as a couch potato!).
