"Elon Musk said that AI companies have effectively exhausted all human-generated data online by 2024, as he revealed during a livestream on X. Musk noted that tech firms may need to rely on synthetic data to train AI models, which poses unique challenges, including accuracy and creativity. Andrew Duncan warned that overusing synthetic data could lead to model collapse, where the quality of AI outputs deteriorates over time. The scarcity of high-quality training data is fueling legal disputes over compensation for creative industries and publishers, as acknowledged by OpenAI."
