Well 30 years ago was when it all started (basically Dr de Grey shaking up gerontology, and the subsequent book Ending Aging), and the first ten years he fought all the problems in old academia and funding research himself. The next 10 was more fighting the “deathists” and trying to get at least some seriously funded adventures on the road and now ten years after that we have bio gerontologists not only wanting to push forward but they also can without jeopardizing their careers, lots of well funded biotech startups (rich people did finally get it) and the first treatments (Dasatinib + Quercetin was the first one IIRC, which can be had over the counter. It’s a senolytic and removes senescent cells) actually exists.

Now we need ways to assess the effectiveness of those treatments in humans (better ways than trying and waiting for 30 years), and see if they actually do rejuvenate, and that’s one another tricky question that lots of people are working on right now, so for me the future is bright.
