Vladimir Leshko: You Will Live Forever If You Choose To
“If you are alive in the next 40 or 50 years, you will be able to decide how long you live.”
Timothy Allen speaks with biomedical engineer Vladimir Leshko about gene therapy, longevity, and why Próspera’s regulatory environment makes human trials possible that are effectively blocked elsewhere.
The conversation begins with the practical question at the heart of Próspera’s appeal to frontier medicine. Leshko explains how the city’s legal framework allows companies like Unlimited Bio to run regulated human trials through clinical partners such as GARM Clinic, using a system that is more flexible than the FDA model without being a lawless free-for-all. He pushes back on the common meme that Próspera lets people “do anything,” arguing instead that the system still relies on review boards, liability, insurance, and clear regulatory pathways.
From there, the discussion moves into the science itself. Leshko explains gene therapy in simple terms: not as a Frankenstein-style rewriting of human nature, but as a way of delivering functioning genetic instructions where the body’s own version is missing or broken. He uses the example of his own son’s inherited deafness to illustrate both the promise and the current limits of the technology, and walks Timothy through embryo selection, embryo editing, viral delivery systems, and why early intervention matters so much.
The episode then broadens into the larger longevity question. Leshko argues that aging should be treated not as an untouchable fact of existence, but as a biological process that can, in principle, be understood and altered. The conversation explores why some species appear to escape aging far better than humans, whether evolution “designed” us to deteriorate, and why current medicine still does almost nothing to slow aging in humans in any meaningful way.
The final third turns philosophical. Timothy pushes the conversation beyond biotech and into the existential territory that longevity inevitably opens up: near-death experiences, lucid dreaming, psychedelics, heaven, suffering, meaning, and whether death is a natural part of life or simply another problem humans have learned to accept too easily. What emerges is less a sales pitch for immortality than a serious attempt to think through what radically extended life would actually mean.
The conversation closes with a striking tension: if AI and technological abundance eventually make much of human struggle optional, what will still give life meaning? Leshko argues that the first moral priority is still obvious – give people the choice not to age into debility and death. Timothy remains more ambivalent, but by the end both men seem to agree on one thing: once the possibility of opting out of aging becomes real, the world will have to rethink far more than medicine.
Enjoy the conversation.
