A new AI video tool called Seedance is causing a stir in Hollywood, with some calling for it to be banned due to copyright concerns, while others are secretly using it to create content. The tool, developed by Bytedance, can generate realistic videos using AI, and has already been used to create a viral video featuring Brad Pitt and Tom Cruise. Despite the controversy, Bytedance is moving forward with its plans to expand in the US, and has even started talks with indie filmmakers about funding AI-generated films. Why it matters: the debate over Seedance highlights the tension between the creative potential of AI and the need to protect intellectual property rights in the entertainment industry.
