My mom used to work at an institute for Vitality and Aging and the leading professor there liked to say that "the first person that will reach a 1000 years of age has already been born"
In any case I'm skeptical for the same reasons as the parent. Until we can do it to a mouse reliably, it's at least 20 years away.
The other thing that people miss is we have cures for a whole lot of things that people still die from in many parts of the world. If this technology was available, I don't see any encouraging precedent that it would become cost effective enough in any normal time horizon to be available to normies like the rest of us.
