Apple's new CEO, John Ternus, is expected to take over from Tim Cook and focus on using AI in all aspects of the company's operations. While other companies are investing heavily in AI research and data centers, Apple's spending has remained relatively flat. Ternan's appointment indicates that Apple will focus on running powerful AI models on its own hardware, not in data centers. The company's personal AI models would be located in a secure enclave within an Apple chip, similar to Apple Pay, which keeps financial information invisible to the user. The importance of data security and privacy will increase as distrust of big AI labs grows and regulators lag.
