WSJ's The Future of Everything welcomes Hany Farid, a professor of computer science at the University of California, Berkeley. He discusses the rising prevalence of fake images created through generative AI and the potential problems it may cause. Farid explores the ease at which convincing fake images can be produced and the need for tech solutions to identify their authenticity. The podcast delves into the risks of AI-generated content, the continuous improvement of AI-generated imagery, techniques for synthetic image generation, and the necessity of multiple solutions to address disinformation.
AI-generated content poses serious risks to privacy, trust, and democracy.
Combining technology, regulation, industry leadership, and media literacy is crucial in mitigating the spread of fake content.

The Risks of AI-Generated Content
AI-generated content, such as fake images, videos, and audio, poses serious risks to individuals, governments, and financial markets. The increasing realism and accessibility of this technology make it difficult for the average user to distinguish between real and fake content, creating threats to privacy, trust, and democracy.
Advancement of AI-Generated Content
AI-generated content has come a long way in a short period of time. From initial low-quality and glitchy deep fakes, the technology has rapidly improved, allowing for the creation of high-resolution, real-time, and almost indistinguishable fake images. Voice synthesis has also caught up, enabling the recreation of human-like audio. However, video synthesis is still lagging behind.
Addressing the Issue of AI-Generated Content
The battle against AI-generated content requires a multifaceted approach. Passive techniques like post-hoc analysis can help detect fake content, but they have limitations in dealing with the scale of the internet and non-consensual uses. Initiatives like the Content Authenticity Initiative (CAI) propose watermarking and fingerprinting every piece of content generated, allowing browsers to indicate whether an image is authenticated or computer-generated. Combining technology, regulatory pressure, industry leadership, and media literacy is crucial to mitigating the spread and impact of fake content.
Fake images are already turning heads online, and Hany Farid, a professor of computer science at the University of California, Berkeley, says we’re only going to see more of it. Farid specializes in image analysis and digital forensics. He tells WSJ’s Alex Ossola why it’s so easy to use generative AI to create convincing fake images, and why it could cause problems in the future. Plus, he discusses the potential tech solutions that will help us decipher whether an image or video we’re seeing online is too good to be true.
