Elon Musk threatened to ban Apple devices at Tesla and his other companies if Apple integrates OpenAI technology directly into its operating system. He sees this as an "unacceptable security violation." Visitors would have to check their Apple devices "at the door, where they will be stored in a Faraday cage" if such an integration occurred. Apple partnered with OpenAI to bring ChatGPT technology to its devices, emphasizing privacy with a combination of on-device and cloud processing. Musk argued it is "patently absurd" for Apple to claim it can't make its own AI but ensure OpenAI protects security and privacy. Musk, who co-founded and later sued OpenAI for deviating from its mission, has established his own AI company, XAI.
