This claim is partially true but significantly overstated. The U.S. Copyright Office concluded in 2025 that existing copyright law is "flexible enough" for AI copyrightability questions and recommended no new legislation. However, major issues—particularly whether AI training on copyrighted data constitutes fair use—remain genuinely unresolved, with landmark cases like NYT v. OpenAI still pending. The blanket claim of "insufficiency" conflates unsettled legal questions (normal in evolving areas of law) with doctrinal failure, and lumps together issues where existing law is adequate with those still being litigated.
