Honestly I also get your take. I think it will depend on the "thing" that will enable us to live longer and healthier.

If it is something very expensive and an overnight discovery, then it is likely that a dystopian era will occur... Just imagine some kind of tyrant (as a reference to the fable!) reigning over a country for 100+ years.

But it could also be somewhat like what happened with medicine: the sum of smaller improvements, some more expensive than others, years after years.

If a tyrant reigns over a country for centuries, it's because the people there want him in power.
