Nobel laureate Venki Ramakrishnan discusses the science of aging and longevity, debunking hype around living forever while explaining the molecular damage that causes aging. He argues that radical life extension is highly unrealistic despite billionaire investments, and emphasizes the importance of healthspan over lifespan.

Venki Ramakrishnan dismisses claims of living forever as 'highly unrealistic,' comparing it to colonizing other galaxies in difficulty.
He criticizes tech billionaires for treating life as a software problem, noting the analog world of medicine requires real-world solutions.
Molecular damage from DNA, cellular senescence, and mitochondrial dysfunction accumulate with age, despite sophisticated repair mechanisms.
Demis Hassabis's prediction of no illnesses within 10-15 years is labeled 'over-optimistic' due to the complexity of drug development.
Ramakrishnan suggests moderate eating and GLP1 drugs may improve healthspan, but stresses enjoying life over obsessing about longevity.
"I think there's no physical or chemical law saying that our lifespan has to be what it is today. But saying there's no physical law doesn't mean anything because... it's incredibly hard."
"They have the bias of looking at the entire world as if it's a software problem. And the world is not digital, the world is analog."
"They're all middle-aged men, often married to younger women, which is a strong incentive to want to live longer."
