I believe that much of our fundamentalism about maximising lifespan is fueled by fear of a swing in the opposite direction. The slippery slope from "it's ok to not always maximise" to "people routinely get shamed into agreeing to euthanasia" and beyond isn't just imaginative. But I believe that it's one of those slippery slopes where we need to make up our minds about where we want to be and learn to stand there, despite the slickness and the angle. Because there is no easy ground anywhere near, we could keep human cell cultures that once were a person metabolizing for decades if we really wanted (and if it was done at scale it would make life hell for the actually living).
