Variations of cryonics — the long term storage of human beings, usually at low temperatures — have long been featured in science fiction. In stories involving space travel, it’s often used as a solution for long-duration journeys. But increasingly, this is not just the stuff of fiction anymore.

The prospect of preserving ourselves, potentially indefinitely, forces us to ask some of the most profound questions we have ever faced: are we meant to transcend the boundaries of our mortal lives? What does it mean to be alive? If life can be extended, what happens to its meaning, urgency, and beauty? These questions, by turns technological, philosophical, ethical and even spiritual, are what we explore in this episode.

Ariel Zeleznikow-Johnson, PhD is a neuroscientist who studies the nature of conscious experiences to better understand how we can preserve cognitive function. His book The Future Loves You: How and Why We Should Abolish Death (2024), explores the viability of delaying death and its societal implications. Over the course of our conversation, we discuss the science of human preservation, definitions of life and death, broader questions about how we derive meaning from life, whether or not the finitude of human experience is essential to our conceptions of a well-lived life, our social contract with future generations, and more.
