If something like this ever becomes a practical application on the organismal level, the octogenarian dictators of the world will rejoice.

Slightly tangential: Michael Levin’s work on bioelectricity and cell reprogramming is pretty interesting in context of emergent behaviors in groups of cells. https://en.wikipedia.org/wiki/Michael_Levin_(biologist)

My nightmare is that we solve aging just in time for the Baby Boomers to live forever.

Because this is the worst timeline, we're getting cell reprogramming used to grow artificial brains to run AI workloads before functional aging remediation... let alone GTA VI.

It may be a dumb reason to do it, but recently I've started to focus on my health a bit more because of news like this (more exercise and healthier food). The thinking is, if we find a way to massively extend the human lifespan/reverse aging I want to live long enough for that. I'd be pissed if we as humanity solved aging and I die just before that, not taking any chances.

Sounds like the immortal jellyfish solution. We squeeze entropy out of our DNA by creating a new fresh cell (ovum) that’s very sensitive to genetic defects, meaning if it survives it’s probably good. The jellyfish just shrinks back to a single cell (presumably with some mechanism for keeping the ‘best’ cell) to reset the damage. This is doing the same thing, but piece by piece. Edit: And wow, that abstract appears to have eaten an entire thesaurus.
