PhysicsForums and the Dead Internet Theory
"Hall of Impossible Dreams" is a repository featuring diverse content, including code and literature, and recently discussed the decline of PhysicsForums due to AI-generated content. PhysicsForums, established in 2001, was a thriving science forum until the rise of centralized platforms like StackExchange and the infiltration of AI-generated posts by 2025. The post raises concerns about the "Dead Internet Theory," which posits that much of the internet is now non-human content, highlighting the challenges and ethical implications of sustaining online communities in the face of evolving technology.
