GPT-6 Astra's integration with robot arms marks a leap in AI-physical system synergy, raising new questions about control and safety. Meanwhile, debates over LLMs as "cognitive viruses" and the limitations of the "next-token predictor" model challenge how we understand and regulate AI's influence on human cognition. These developments highlight the urgency of rethinking AI's role in society.
