Evolution designed us to die fast; we can change that — Jacob Kimmel

Dwarkesh Podcast

Shownote

Jacob Kimmel [https://x.com/jacobkimmel] thinks he can find the transcription factors to reverse aging. We do a deep dive on why this might be plausible and why evolution hasn’t optimized for longevity. We also talk about why drug discovery has been getting exponentially harder, and what a new platform for biological understanding to speed up progress would look like. As a bonus, we get into the nitty gritty of gene delivery and Jacob’s controversial takes on CAR-T cells. For full disclosure, I am an angel investor in NewLimit. This did not impact my decision to interview Jacob, nor the questions I asked him.

Highlights

In this episode, Dwarkesh Patel sits down with Jacob Kimmel, Co-founder & President of NewLimit, to explore the cutting-edge science behind aging and the ambitious goal of reversing it. The conversation delves into the biological and evolutionary reasons why longevity hasn't been a priority for natural selection, how modern biotechnology could overcome these limitations, and the challenges facing drug discovery today. With insights into epigenetic reprogramming, synthetic biology, and delivery mechanisms like viral vectors, this discussion offers a deep look into the future of medicine and the potential for extending human healthspan.
