Cleo Abrams did a good video on that and her conclusion is that if the stuff does work it’s not some magic reversal or absolute no aging ever technology, I think we’ve got a whole world away before we can get no aging. Adding a few years to someone’s life or more realistically preventing diseases due to faulty organs is something we can all benefit from. I don’t even know if this stuff will be done during my lifetime but I can hope that the next generation won’t have to watch themselves break down slowly.
