This episode of TecHype features Yoel Roth, former Head of Trust and Safety at Twitter. Yoel provides first-hand insights into how one of the largest online platforms in the world built out its trust and safety operations to better ensure its service was helpful, harmless, and aligned with user expectations

While at Twitter, Dr. Roth found himself the target of a coordinated harassment campaign on the platform, one instigated by the current CEO Elon Musk. His years of work building out the trust and safety operations had become personal. In this episode, Dr. Roth provides professional and personal perspectives on the real benefits and risks of platform trust and safety efforts, the current state-of-the-art of the field, and where it’s going.

TecHype is a groundbreaking series that cuts through the hype around emerging technologies. Each episode debunks misunderstandings around emerging tech, provides insight into benefits and risks, and identifies technical and policy strategies to harness the benefits while mitigating the risks.

This episode of TecHype features Prof. Stuart Russell from UC Berkeley, a world-renowned expert in artificial intelligence and co-author (with Peter Norvig) of the standard text in the field. We debunk misunderstandings around what “AI” actually is and break down the benefits and risks of this transformative technology. Prof. Russell provides an expert perspective on the real impacts AI will have in our world, including its potential to provide greater efficiency and effectiveness in a variety of domains and the serious safety, security, and discrimination risks it poses.

UC Berkeley engineers have created a simple and low-cost new arsenic treatment system to help low-income communities access safer water.

In many areas throughout California, the groundwater is tainted with dangerous levels of arsenic, a highly carcinogenic element that can seep into the water table from deposits in the soil and bedrock. While cities and larger municipalities can afford to remove arsenic from their water, many people living in small and rural communities are forced to choose between drinking contaminated tap water or purchasing bottled water — and those with private wells may not even know that their water is unsafe.

Researchers deployed a fleet of 100 semi-autonomous vehicles to test whether a new AI-powered cruise control system can help smooth the flow of traffic and improve fuel economy.

In a massive traffic experiment, scientists tested whether introducing just a few AI-equipped vehicles to the road can help ease “phantom” jams caused by human behavior and reduce fuel consumption for everyone.

TecHype is a groundbreaking series that cuts through the hype around emerging technologies to get to what matters. Each episode debunks misunderstandings around emerging tech, provides insight into benefits and risks, and identifies technical and policy strategies to harness the benefits while mitigating the risks of emerging technologies. This episode of TecHype features Prof. Hany Farid from UC Berkeley, a world-renowned expert in the analysis of digitally manipulated images. We take a deep dive into determining what a 'deepfake’ is and explore how these AI-generated images, videos, and audio can be used for both amusing and alarming purposes.

Farid highlights the increasing prevalence of deepfakes and their impact on society. From revolutionizing the entertainment industry, bolstering creativity, and championing advocacy campaigns to their use in impersonating public figures in ways that manipulate elections or personal contacts to commit fraud. The episode concludes with a discussion of targeted strategies that can be pursued to keep you safe from harmful deepfakes, such as digital watermarking and detection tools.

UC Berkeley drills a 400-foot borehole to explore geothermal heating on campus.

UC Berkeley plans to decommission its 40-year-old cogeneration plant and replace its current steam heating system with a new system that uses water pipes to heat and cool buildings on campus. While the cogeneration plant burns natural gas to produce electricity and steam heat for the campus, the new system will use electricity for both power and thermal needs. By using clean energy sources, such as wind and solar, to produce this electricity, the campus’s future power, heating and cooling needs would be entirely carbon-free.

Using real-life examples and historical evidence, French anthropologist Philippe Descola aims to understand the unique characteristics of communities that exist outside of modern societies. These communities have often been misunderstood because they were mistakenly compared to nation-states. However, Descola argues that we should examine the components and relationships within these communities based on how they perceive the world. By doing so, we can challenge the Eurocentric and human-centric view of social structures, which rely on Western ideas of progress and functionality.

In this program, scholars Philippe Descola, Adom Getachew, Timothy LeCain and David Wengrow discuss how views of humans verses non-humans shaped the modern world. Series: "Tanner Lectures on Human Values" [Humanities] [Show ID: 38618]

This series on artificial intelligence explores recent breakthroughs of AI, its broader societal implications and its future potential. In this presentation, Pamela Samuelson, professor of Law and Information at UC Berkeley, discusses whether computer-generated texts and images fall under the copyright law. She says that early on, the consensus was that AI was just a tool, like a camera, so humans could claim copyright in machine-generated outputs to which they made contributions. Now the consensus is that AI-generated texts and images are not copyrightable for the lack of a human author. The urgent questions today focus on whether ingesting in-copyright works as training data is copyright infringement and whether the outputs of AI programs are infringing derivative works of the ingested images. Four recent lawsuits, one involving GitHub’s Copilot and three involving Stable Diffusion, will address these issues.

Samuelson has been a member of the UC Berkeley School of Law faculty since 1996. She has written and spoken extensively about the challenges that new information technologies pose for traditional legal regimes, especially for intellectual property law. She is a member of the American Academy of Arts & Sciences, a fellow of the Association for Computing Machinery (ACM), a contributing editor of Communications of the ACM, a past fellow of the John D. & Catherine T. MacArthur Foundation, a member of the American Law Institute, and an honorary professor of the University of Amsterdam. Series: "Data Science Channel" [Science] [Business] [Show ID: 38859]
