1297. Biohacking Priests: The Religion of Anti-Aging That’s Defying Death – with Stephen Cave

In this episode of The Human Upgrade, Host Dave Asprey sits down with philosopher and longevity scholar Dr. Stephen Cave to explore why the quest to defy death is no longer just science—it’s becoming a belief system. They examine how biohacking, nootropics, and human performance tools are shaping a new cultural movement around immortality, and why boredom, ego, and procrastination may be the biggest obstacles to living longer. You’ll learn about the four immortality narratives found in every culture, the ethics of mind uploading, and why hacking your biology with smarter tools like cold therapy, fasting, and supplements is only half the story. This conversation dives deep into neuroplasticity, purpose, AI, and why true longevity may demand more than just mitochondrial upgrades.

What if death isn’t inevitable but a solvable problem? This episode explores how biohacking is reshaping our understanding of mortality, legacy, and the limits of human performance. You’ll learn why some of today’s top thinkers are treating longevity as both a science and a spiritual movement, and how this shift affects your brain, your mitochondria, and your entire approach to life. 

Host Dave Asprey sits down with philosopher and best-selling author Dr. Stephen Cave, Director of the Institute for Technology and Humanity at the University of Cambridge. With decades of expertise studying death, immortality, and ethics, Dr. Cave brings a rare depth of insight into how our desire to live longer intersects with neuroplasticity, supplements, and even nootropics. 

Together, they unpack the four universal immortality narratives, the dangers of mind uploading, and why AI might become humanity’s next god or destroyer. You’ll discover how legacy, ego, functional medicine, and even fasting and ketosis play into our fear of death. The conversation also dives into the deeper psychological and societal consequences of radical life extension, and what happens when biohacking crosses into belief. 

This episode is a must-listen for anyone serious about hacking longevity, brain optimization, metabolism, and building a future where living to 180 isn’t science fiction. You’ll also hear surprising thoughts on Danger Coffee, RFK, sleep optimization, and how to approach mortality using the Smarter Not Harder mindset.
