MIT professor Max Tegmark has issued a warning that AI tech companies are caught in an out of control race. He calls for a six-month pause on the development of large AI systems, but this has not been successful. Tegmark warns that AI development could spiral out of control, urging government intervention. He emphasizes that models should not be enhanced, nor should dangerous technologies be open-sourced until safety standards are met. Concerns have been raised about the development of AI, including issues related to deepfake videos and potential threats.
