It's kind of a false dilemma? Old persons who don't change versus young ones who do? Could be ageist, not to mention neglecting the real issue of experience. I agree with the "room for new people" conundrum but you could approach that as a population control issue from a couple of different directions. Or you could approach lifespan extension simultaneously with research on its consequences, like how to structure society (economics, politics, etc) so as to optimize well-being.
