Jacob Kimmel, the Co-founder & President of NewLimit, 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 already 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, not the questions I asked him.

How will we feed the 100s of GWs of extra energy demand that AI will create over the next decade? On this episode, Casey Handmer (Caltech PhD, former NASA JPL, founder & CEO of Terraform Industries) walks me through how we can pull it off, and why he thinks a major part of this energy singularity will be powered by solar. His views are contrarian, but he came armed to defend them.

A deep dive with Lewis Bollard, who leads Open Philanthropy’s strategy for Farm Animal Welfare, on the surprising economics of the meat industry.

Why is factory farming so efficient? How can we make the lives of the 23+ billion animals living on factory farms more bearable? How far off are the moonshots (e.g., brainless chickens, cultivated meats, etc.) to end this mass suffering? And why does the meat industry have such a surprising amount of political influence?

For decades, innovation in the meat industry has actually made the conditions for animals worse. Can the next few decades of tech reverse this pattern?

Donation match fundraiser

The welfare of animals on factory farms is so systemically neglected that just $1 can help avert 10 years of animal suffering.

After learning more about the outsized opportunities to help, I decided to give $250,000 as a donation match to farmkind.giving/dwarkesh. FarmKind directs your contributions to the most effective charities in this area.

Please consider contributing, even if it’s a small amount. Together, we can double each other's impact and give a total of $500,000.

Bluntly, there are some listeners who are in a position to give much more. Given how neglected this topic is, one such person could singlehandedly change the game for 10s of billions of animals. If you’re considering donating $50k or more, please reach out directly to Lewis and his team by emailing andres@openphilanthropy.org.
