Quora, once a high-quality question-and-answer community, has gradually transformed into an internet garbage platform. The AI chatbot Poe has failed to address Quora's issues, leading to phenomena of AI-generated questions and answers. The community culture has vanished, with long-standing users leaving and new users showing disdain. Commercialization has encountered obstacles, making profitability challenging. The involvement of AI has resulted in a decline in quality, manifesting as AI-generated questions and answers.
