human biology at the molecular level is so much more complicated than just "turn a couple of genes on and off", especially for something as all-encompassing as aging, and there are so many mechanisms and interactions that vary massively even just between different call types and organs and we are nowhere near close to even scratching the surface of understanding. maybe this does do something noticeable for a couple of things like hairs going grey or whatever visible indicators of age but who knows what other shit its doing and even best case that its not making anything worse, i can pretty much guarantee its not reversing anywhere near all the effects of aging. obvious thing to me off the top of my head is ending up riddled with cancer cos some of the stuff that makes us age is a kinda trade-off with anti-cancer mechanisms.

and yeah this "oh yeah itll be through trials and ready for sale in 10-15 years" stuff, lol come on guy. there might be something interesting and useful under all this sales pitch stuff but he is massively overselling
