What is the future of longevity?

The future of longevity is more healthy years, not just more years. I predict biotech, AI, diagnostics, and personalized medicine extend healthy human lifespan significantly, and the focus shifts from treating disease to preventing, delaying, and potentially reversing aging itself. The longevity economy hits $20 trillion a year by 2030. Follow the money: Jeff Bezos backs Altos Labs, Sam Altman backs Retro Biosciences, Bryan Johnson spends $2 million a year on his own body, and Novo Nordisk and Eli Lilly now sell their weight-loss drugs as the first longevity pills. Watch who sells you the subscription: big pharma never found a cure in its life, because cures kill subscriptions. I frame longevity as several exponential technologies hitting medicine at once. The question is no longer if, but how soon, and for whom. My warning stays: no pill beats real food and a body you actually use.
