Agreed, what you describe is the status quo, where we have small evolutions through diets and drugs.

But I'm not completely on the pessimistic side because there's one thing that could change everything: the moment someone discovers how to effectively revert human cell decay (which has already been done in lab rats btw), then reality changes completely and living to 200 and beyond is achievable.

It could very well be like turning lead into gold, an ideal so close but never achieved. But on aging, I think humans already know what needs to be done, so I wouldn't put all my bets against it.

Pedantic quibble, but by "never achieved" you probably mean "too inefficient to do in practice?" For lead to gold in particular, all you really need is a particle accelerator, a steady supply of energy, and a lot of patience.
