  I always see this guy antagonizing everyone (David Sinclair, Aubrey de Grey, etc.). Is he the Gary Marcus of longevity?

  So he's saying they didn't fix aging, they just fixed some simpler damage they did themselves. But in a previous experiment, the same treatment improved aging damage to the vision of actually old mice: > Sinclair and colleagues injected the reprogramming-factor genes into the eyes of 1-year-old healthy mice, roughly the mouse equivalent of middle-age. By this stage, the animals had visual acuity scores about 15% lower than their 5-month-old counterparts. Four weeks after treatment, older mice had similar acuity scores to younger ones. https://www.science.org/content/article/researchers-restore-lost-sight-mice-offering-clues-reversing-aging https://www.science.org/content/article/researchers-restore-...
