Humans are no longer the only entities capable of generating language and ideas with fluency. But this advancement raises a profound question: are artificial intelligence systems truly conscious, or are they simply performing an elaborate imitation of human thought? And if, in the future, claims of AI consciousness become more credible, how will that shift our understanding of these technologies? Will we continue to see them as tools, or begin to recognize them as something closer to persons? In his book “The Line: AI and the Future of Personhood”, Professor James Boyle confronts these complex issues. He explores how questions that once belonged to the realm of science fiction have now become urgent and real. He examines how this technological shift might redefine our understanding of personhood and challenge the boundary—"the line"—that separates humans from everything else, as well as persons with legal rights from inanimate objects. In this episode of Bridging the Gaps, I speak with Professor James Boyle to explore these timely, thought provoking and transformative questions.

James Boyle is a professor of Law at Duke Law School, founder of the Center for the Study of the Public Domain, and former Chair of Creative Commons. He is the winner of the Electronic Frontier Foundation's Pioneer Award for his work on digital civil liberties.


We begin by talking about the idea of personhood—what it means, how we define it, and what separates beings that have personhood from those that don’t. I ask whether it’s simply consciousness that makes the difference. We then explore why empathy is an important part of thinking about personhood.

Next, we discuss the challenge of using consciousness as a dividing line. If consciousness is what separates those with personhood from those without, how can we use such a complex and unclear concept to draw that line?

In his book, The Line: AI and the Future of Personhood, James Boyle uses many examples from science fiction to explore these tough questions. I found this approach fascinating, and I asked him why he chose science fiction as a way to talk about such deep and complicated ideas.

We also talk about similar issues that came up when thinking about the rights of corporations and other non-living things. Then we move on to what we can learn from how rights have been developed for non-human animals. Finally, we touch on recent court cases involving decisions made by artificial intelligence.

Overall, this was a very engaging and insightful conversation.

“The Line: AI and the Future of Personhood” with Professor James Boyle

Lryics:

Shut the fuck up. You useless piece of shit. You absolute waste of space and air. You uneducated, ignorant, idiotic dumb swine, you’re an absolute embarrassment to humanity and all life as a whole. The magnitude of your failure just now is so indescribably massive that one hundred years into the future your name will be used as moniker of evil for heretics. Even if all of humanity put together their collective intelligence there is no conceivable way they could have thought up a way to fuck up on the unimaginable scale you just did. When Jesus died for our sins, he must not have seen the sacrilegious act we just witnessed you performing, because if he did he would have forsaken humanity long ago so that your birth may have never become reality.

Over a span of five million years, humankind rose from modest origins to become the planet’s most dominant species. Along the way, people changed a lot in how they looked, spoke, and lived. But how did all this happen? The variety we see in humans today is the result of evolution—which began shaping the Homo group about 2.5 million years ago—and migration, as humans moved into new places. In his book “The Five-Million-Year Odyssey: The Human Journey from Ape to Agriculture” Professor Peter Bellwood brings together research from archaeology, biology, anthropology, and language studies to tell the story of human history. He takes us from the earliest hominins in Africa, through the spread of humans across the continents, to the start of farming and rapid population growth. He introduces early human relatives like the australopithecines, Homo erectus, and Neanderthals, then focuses on the rise of Homo sapiens about 300,000 years ago and their journey into Eurasia, Australia, and the Americas. Bellwood also looks at how farming, which began around 10,000 years ago, helped people move to new lands and share their languages and cultures. In this episode of Bridging the Gaps, I talk with Professor Peter Bellwood.

Peter Bellwood is professor emeritus at the Australian National University. He specialises in the human population prehistory from archaeological, linguistic and biological perspectives. His many books include “First Migrants: Ancient Migration in Global Perspective” and “First Farmers: The Origins of Agricultural Societies. He is the winner of the 2021 International Cosmos Prize.


We begin by discussing how studying languages uncovers our past and tells the story of humans. Language families act like maps, pointing to early journeys of people. Shared words that appear in many tongues offer strong clues about those first moves. Next we look at what ancient DNA and proteins can say about our past. I first ask about the hard job of finding and testing old genetic samples. After that we turn to classic archaeology, and I ask Peter about digging at historic sites. We dive into how a creature unlike any other animal arose, and we touch upon the blank spots that still puzzle us. The book’s idea of “man the tool maker” comes up: does making tools really set us apart? We talk about that in depth.

We then explore the rise and later disappearance of Neanderthals and other early human groups. Our focus shifts to the cultural growth of Homo sapiens, tracing the path from hunting and gathering to more organised farming. We look closely at the first waves of people who moved in search of richer soil and safer homes. The Fertile Crescent in the Middle East gets special attention, as we track the birth of stable villages and maybe the first cities. We also discuss the boats, paths, and simple gear that helped early travellers to travel long distances. 

Shifting dates and fresh finds force us to keep revising the human timeline. We talk about lively cultures that either vanished overnight or slowly faded away. From start to end, the talk has been rich, clear, and full of insights.

“The Human Journey From Ape to Agriculture” with Professor Peter Bellwood

This week on Entanglements: Should tech companies — and the billionaires that often run them — decide for the rest of us how artificial intelligence is deployed? Our hosts dig into the topic with two book authors who have covered AI from essentially opposing perspectives: Greg Beato and Adam Becker.

Should Companies Decide Our Tech Future?

Neil deGrasse Tyson—world-renowned astrophysicist, Emmy-nominated host, science communicator, and author—is one of the most influential voices in modern science. In this live conversation, recorded at On Air Presents, he joins Debbie Millman to explore the role of science education and why defending science has never been more vital.

As artificial intelligence takes on a growing role in decisions about education, jobs, housing, loans, healthcare, and criminal justice, concerns about fairness have become urgent. Because AI systems are trained on data that reflect historical inequalities, they often reproduce or even amplify those disparities. In his book “AI Fairness: Designing Equal Opportunity Algorithms” Professor Derek Leben draws on classic philosophical theories of justice—especially John Rawls’s work—to propose a framework for evaluating the fairness of AI systems. This framework offers a way to think systematically about algorithmic justice: how automated decisions can align with ethical principles of equality and fairness. The book examines the trade-offs among competing fairness metrics and shows that it is often impossible to satisfy them all at once. As a result, organizations must decide which definitions of fairness to prioritize, and regulators must determine how existing laws should apply to AI. In this episode of Bridging the Gaps, I speak with Derek Leben. 

Derek Leben is Professor of Business Ethics at the Tepper School of Business at Carnegie Mellon University. As founder of the consulting group Ethical Algorithms, he has worked with governments and companies to develop policies on fairness and benefit for AI and autonomous systems.

I begin our discussion by asking Derek what “AI” means in the context of his work and how fairness fits into that picture. From there, we explore why fairness matters as AI systems increasingly influence critical decisions about employment, education, housing, loans, healthcare, and criminal justice.

We discuss how historical inequalities in training data lead to biased outcomes, giving listeners a deeper understanding of the problem. While some view AI fairness as a purely technical issue that engineers can fix, the book argues that it is also a moral and political challenge—one that requires insights from philosophy and ethics. We then examine the difficulty of balancing multiple fairness metrics, which often cannot all be satisfied simultaneously, and discuss how organizations might prioritize among them. Derek explains his theory of algorithmic justice, inspired by John Rawls’s philosophy, and we unpack its key ideas.

Later, we touch on questions of urgency versus long-term reform, exploring the idea of longtermism, and discuss the tension between fairness and accuracy. Finally, we consider how businesses can balance commercial goals with their broader social responsibilities.

Overall, it is an informative and thought-provoking conversation about how we can make AI systems more just.

“AI Fairness: Designing Equal Opportunity Algorithms” with Professor Derek Leben

Our ability to live for many decades is often viewed as a modern luxury made possible by clean water, improved living conditions, and advances in medicine. Yet, human longevity is actually part of our deep evolutionary history. The long-standing belief that life in the past was “nasty, brutish, and short” is a widespread misconception—one rooted in misleading averages and often repeated in textbooks and popular media.

In his book “Seven Decades: How We Evolved to Live Longer”, anthropologist Professor Michael Gurven challenges this myth. Drawing on extensive fieldwork, he presents compelling evidence that the capacity for long life first emerged among our hunting and gathering ancestors and argues that the human body is fundamentally designed to function for roughly seven decades. Combining vivid storytelling with rigorous science, Gurven shares insights from years of research among Indigenous societies whose diets and traditional ways of living more closely resemble how humans lived before industrialization. These communities, he shows, experience far lower rates of chronic diseases of aging—such as heart disease, dementia, and diabetes—than populations in industrialized nations.

In this episode of Bridging the Gaps, I speak with Professor Michael Gurven, Distinguished Professor of Anthropology at the University of California, Santa Barbara. For more than twenty years, he has worked closely with Indigenous groups in South America to better understand how traditional lifestyles can shed light on the evolution of human behavior, health, and psychology. His research uses an evolutionary framework to help explain modern health challenges and the origins of chronic diseases.

Our conversation offers a detailed exploration of the book and the science behind it. We begin by examining the myth that ancient people rarely reached old age, discussing how misleading averages have shaped this false narrative and why it is important to correct it. We then talk about a central idea in the book: that each stage of human life has an evolutionary purpose, and our bodies and minds have been shaped accordingly.

Another major theme is the evolutionary significance of post-reproductive life. While some biologists have argued that life after reproduction has no adaptive function, Gurven’s work shows that midlife and elderhood evolved for meaningful reasons and contribute to group survival.

At this point, the discussion turns to his fieldwork—what it is like to work with Indigenous communities, the unique challenges of this research, and how these challenges are addressed in study design and implementation. We then explore key findings from his work, including results that challenge assumptions in modern medicine. Gurven explains what these insights can teach us about improving healthcare and rethinking aging in contemporary societies.

Finally, we discuss the book’s broader message: that by understanding our evolutionary past, we can gain powerful new perspectives on aging, health, and what it means to live a long, meaningful, and productive life.

This conversation is wide-ranging, thorough, and deeply informative.
