Elon Musk has delivered a harsh warning in reaction to Apple's recently announced alliance with OpenAI. The CEO of Tesla and SpaceX has warned that Apple products would be banned at his firms if OpenAI's ChatGPT is integrated at the operating system level, calling it "an unacceptable security violation."

Musk's comment follows Apple's announcement of "Apple Intelligence," a set of AI-powered capabilities integrated into iOS 18, iPadOS 18, and macOS Sequoia. Apple Intelligence takes use of Apple silicon's ability to interpret and produce words and graphics, streamline processes across apps, and draw on personal context to ease daily routines.

"We are excited to launch a new chapter in Apple innovation. Apple Intelligence will change what people can do with our devices—and what our products can do for them," stated Tim Cook, Apple's CEO. "Our novel technique blends generative AI with a user's particular context to provide really useful intelligence. And it can access that information in a fully private and secure manner, allowing users to focus on what is most important to them. This is AI as only Apple can provide it, and we can't wait for people to see what it can achieve.

While Apple has emphasized its dedication to user privacy, with many AI operations taking place on-device and more complicated functions requiring secure cloud infrastructure, Musk's concerns appear to derive from a potential deeper integration of OpenAI's technology into Apple's core systems.

Musk, who runs the AI business xAI, reiterated his position in a subsequent tweet: "And visitors will have to check their Apple devices at the door, where they will be stored in a Faraday cage."
