The Edge

It's hardly news that California's income gap is among the widest in the country. But how do Californians make sense of economic inequality? Berkeley sociologists G. Cristina Mora and Tianna S. Paschel investigated how the Los Angeles and Central Valley middle class—those who “feel the promise and precarity of California most acutely”—thinks about this gnawing gap, and what stories help them justify it.

It’s the age of AI. Robots are getting smarter and learning to do our jobs at an alarming rate. And the question no one seems to be able to answer is: Will robots replace us all and rule the world? Or will we find a way to work in harmonious productivity? That question might be missing the point, says Berkeley grad Annalee Newitz. An award-winning science journalist, fiction writer, and podcast host, Newitz talks about why the debate in AI may be misguided and how sci-fi can be a tool, not merely as escapism, but as a means of imagining our way to a better future.

When you send a message to a friend—whether by text, email, or social media—you probably don’t think much about where it’s actually going. We’ve grown so accustomed to our free-floating devices and digital clouds and seemingly wireless connectivity that we might not realize just how wired our digital world truly is. The reality is, every message we send travels through a vast physical system: routers, cell towers, data centers, power grids, and miles of undersea and terrestrial fiber networks. And every part of it depends on human decisions. This means that the future of digital infrastructure depends not just on engineers but on policymakers, biologists, economists, designers, even journalists. But how do we bring all these people together?

Nicole Starosielski, professor of Film and Media at UC Berkeley, is working on exactly that. She studies the hidden physical systems that make the internet possible—from undersea cables to global media networks to the environmental costs of connectivity—and is training a new generation of leaders who can navigate this field across all dimensions.

For decades, researchers believed that whales communicated using a sort of underwater Morse code—simple, repeated patterns of clicks. But recent advances in technology have revealed a much more complex, even human-like language. Now, with artificial intelligence, scientists are getting closer than ever to translating their vocalizations. UC Berkeley’s Gašper Beguš is one such researcher building advanced AI to learn and decipher sperm whale communication. But what happens when we crack the code? What might whales tell us—and what would be the practical, ethical, and legal implications of what we learn?

Wild Wild Country. Escaping NXIVM. The Path. Holy Hell. That’s just a few of the vast and growing collection of documentaries, podcasts, docuseries exploring the history and legacy of cults. What explains this explosion of interest? Associate professor of English and resident cult expert Poulomi Saha joins Editor-in-Chief Pat Joseph live onstage to discuss America’s long enthrallment with—and participation in—cults.

No doubt you’ve heard a thing or two about Bad Bunny recently. He’s a rapper, singer, and producer, also known as the “King of Latin Trap”—and reggaeton, of course—who’s soon to become the first solo Latino to headline the Super Bowl. But he’s also Benito Antonio Martínez Ocasio, a 31-year-old from Puerto Rico and an outspokenly political artist, using his platform and music to address humanitarian crises, gender-based violence, and political corruption. Our guest today is Petra Rivera-Rideau, an expert in music and racial politics who completed her Ph.D. at UC Berkeley and also holds the distinct honor of having taught the first-ever (as far as we know) course on Bad Bunny. She talks about her latest book, P FKN R: How Bad Bunny Became the Global Voice of Puerto Rican Resistance, Bad Bunny’s artistic and political legacy, and the rise of popstar-studies in academia.

Some Catholics no doubt took offense, but no one was seriously harmed by the Pope-in-a-puffer-jacket meme. Far more sinister deepfakes are on the rise, however, with scammers now frequently using widely available technology to bilk the unwary, and political campaigns marshaling AI to sow lies about their opponents. Perhaps the greatest threat is not the deepfakes themselves but that their mere existence can cause us to question the veracity of nearly everything we see and hear online and in the media. So, how concerned should we be about the proliferation of fake media? And what, if anything, is being done to staunch the bleeding? UC Berkeley Professor Hany Farid, a pioneer in the field of digital forensics, joins Editor-in-Chief Pat Joseph live onstage to discuss what the growing onslaught of mis- and disinformation portends for our society and what we can do to manage it.

Just over a decade ago, Berkeley computer science professor Stuart Russell, recently named one of TIME’s 100 Most Influential People in AI, warned a lecture audience that achieving artificial general intelligence “would be the biggest event in human history . . . and perhaps the last event in human history.” Since then, the development of superintelligent AI has only accelerated—infiltrating nearly every part of society. So, what does the future hold? Stuart joins Editor-in-Chief Pat Joseph live onstage to discuss the perils and promise of the AI revolution.

There’s a paradox in robotics that says: what’s easy for humans is hard for robots, and vice versa. Complex calculations, for instance, are the domain of machines. Simple motor tasks like picking up an object, on the other hand, can stump a robot. That’s where our guest comes in. Jeff Mahler has spent his career working on improving the capabilities of robotic object manipulation. After completing his postdoctoral work at UC Berkeley, Mahler went on to co-found Ambi Robotics with Stephen McKinley, David Gealy, Matt Matl, and Professor Ken Goldberg, building AI-powered robots for warehouse operations. He talks to us about the state of robot assistants and how soon—if ever—we might expect a full robot revolution.
