Billionaire Elon Musk said on Monday he would ban Apple devices at his companies if the iPhone maker integrates OpenAI at the operating system level.

“That is an unacceptable security violation,” Musk, who is the CEO of electric vehicle maker Tesla and rocket maker SpaceX and owner of social media company X, said in a post on X. “And visitors will have to check their Apple devices at the door, where they will be stored in a Faraday cage.”

Apple and OpenAI did not immediately respond to requests for comment.

Earlier in the day, Apple announced a slew of AI features across its apps and operating platforms and a partnership with OpenAI to bring the ChatGPT technology to its devices.

Apple said it had built AI with privacy “at the core” and it would use a combination of on-device processing and cloud computing to power those features.

“It’s patently absurd that Apple isn’t smart enough to make their own AI, yet is somehow capable of ensuring that OpenAI will protect your security and privacy!” Musk said on X.

It was unlikely that anyone would follow Musk’s lead, Ben Bajarin, CEO of consulting firm Creative Strategies, said, adding that Apple was trying to educate people that private cloud was as secure as keeping data on a device.

Private cloud

“What [Apple] is trying to now add to the narrative is when [data] leaves and goes to the secure private cloud, it’s similarly taking that same user data anonymisation and firewalling of that information to you. Apple really never sees that,” he said.

Musk had sued OpenAI, which he co-founded in 2015, and its CEO Sam Altman at the beginning of March, saying they abandoned the start-up’s original mission to develop AI for the benefit of humanity and not for profit.

He has also founded his own startup, xAI, in a bid to challenge OpenAI and build an alternative to the viral chatbot ChatGPT.
