Harvard Geneticist: "Immortality May Have Already Happened!"

What if living longer isn’t about chasing immortality but about quietly staying one step ahead of aging?

Julian sits down with George Church for a wide-ranging conversation that challenges how we think about longevity, aging, and medical progress. Rather than promising overnight breakthroughs, they explore why extending human life is a complex, multi-layered challenge and why meaningful progress may already be happening so gradually that it’s easy to miss. From the concept of “longevity escape velocity” to the difficulty of measuring aging itself, the discussion reframes what it truly means to live longer and healthier.

Together, Julian and George unpack how advances in gene therapy, multiplex genome editing, and AI-driven protein design are reshaping medicine. The focus moves away from sci-fi fantasies toward real-world applications: reversing age-related diseases, improving targeted drug delivery, shortening clinical trials, and reducing risk. They also explore the ethical, societal, and economic implications of longer lives and why revolutions in science often feel invisible right up until they become impossible to ignore.

George Church is a pioneering geneticist and one of the founding figures of synthetic biology. A professor at Harvard Medical School and MIT, he is known for his groundbreaking work in genome sequencing, gene therapy, CRISPR technologies, and aging research. Over decades, his work has helped shape modern biotechnology, with a focus on reversing age-related diseases, improving human health, and responsibly advancing powerful scientific tools.

What You’ll Learn:

• Why longevity is one of the hardest medical outcomes to measure

• What “longevity escape velocity” actually means—and why it may already be underway

• How gene therapy and multiplex genome editing could reverse age-related diseases

• Why AI’s most meaningful breakthroughs may be happening in biology, not chatbots

• The overlooked importance of drug delivery in safe, effective treatments

• Why scientific progress often feels slow before it suddenly accelerates

• How extending healthspan could reshape society, economics, and human potential
