What happens when we take numbers seriously—not just at face value, but in terms of their actual impact on our lives?

This week, Reid and Aria are joined by UK-based mathematician and media personality Hannah Fry to explore this deceptively simple question. From cancer diagnoses to dating apps, Hannah makes the case that understanding the math behind our decisions—and the "game" we're really playing—is essential to building a better future. 

They discuss why regret minimization is often a better guide than raw percentages in assessing risks; Hannah’s advice on finding love in a sea of swipe-rights; and how a well-framed question can be more powerful than the right answer. Plus, Inflection’s Pi chimes in with a few Jane-Austen-themed math jokes.

What will it take to create AI that is as trustworthy, if not more trustworthy than humans? 

This week, Reid and Aria sit down with Yuval Noah Harari, historian, philosopher, and best-selling author of several books including Nexus, Sapiens and Homo Deus. When it comes to outlook on AI, Yuval, Reid, and Aria agree on the importance of building both human trust in AI and AI that is genuinely truth-seeking, but they differ on how possible it is to achieve. 

Together, they dig into their diverging opinions on the outcomes of the AI revolution, global cooperation, and how AI will learn from humans. They also discuss the differences between intelligence and consciousness, and whether conscious AI is a goal worth pursuing. 

Yuval turns to history to ground his warnings about AI. Even though he’s cautious about technology, he is critical of cynicism. Yuval shares his philosophy on human compassion as a guiding principle that can allow us to steer away from collapse and ultimately, build a better AI future.

Opportunity at Work

What would it look like to keep all living creatures in the loop on the development of new technology?

Reid sat down for a wide-ranging solo discussion with Jane Goodall on that very subject – and more. They talked about how to maintain hope and focus on local impact in today’s often chaotic world, how technology – and AI in particular – might be helpful for conservation, and Jane’s global youth program, Roots & Shoots. Plus, the Jane Goodall institute shared audio from a cutting edge acoustic array that helped them discover a brand new species in Gombe National Park in Tanzania! Jane reflected on her legacy and shared stories about bridging unlikely divides, defying the scientific community early in her career, young people opening their eyes to the natural world for the first time, and so much more.

Thank you to the incredible team at the Jane Goodall Institute and WildMon (L. Pintea, B. Wallauer, K. Harmon, M. Campos, Gabriel Leite, Tomaz Melo, Guilherme Melo, D. A. Collins, D. C. Mjungu) that, with funding from Google, utilized an acoustic array to discover brand new species in Gombe National Park, Tanzania, including Thomas’s Dwarf Galago (Galagoides thomasi).

Aria also asks about the rise of Chinese electric vehicles and why BYD might be “the Tesla of tomorrow;” the geopolitical costs of tariffs; and whether saying “please” and “thank you” to ChatGPT is worth it.

Why can the United States government help make a vaccine in a year but not build a high-speed train in a reasonable timeframe? What if our biggest problems—affordable housing shortages, energy limits, and scientific slowdowns—aren’t inevitable, but chosen?

This week, Reid and Aria sit down with Derek Thompson—staff writer at The Atlantic and host of the podcast Plain English—to explore how a scarcity mindset is holding American society back. They cover how AI can revolutionize scientific discovery; what Operation Warp Speed got right; and why real progress depends on bold policy, not just better technology. Plus, Reid joins Derek in the hotseat for some “Too Much, Too Little, or Just Right?”—a game co-created with ChatGPT to discuss ideas in Derek’s new best-selling book, Abundance.
