Apple's Tim Cook's successor, John Ternus, has officially stepped into the spotlight. (A true master of the craft has no LinkedIn.)

He was the key leader in Mac's transition to self-developed chips. It was he who drove the leap in hardware performance, allowing the MacBook to completely shed its reputation for "overheating and throttling."

He is the father of the iPad: involved in the development of every generation. Even more hardcore, he once convinced software chief Craig Federighi to create iPadOS, because he firmly believed the hardware's potential shouldn't be constrained by a phone OS.

• A stickler for hardware details: From the micro-precision assembly of AirPods to the magnetic charging solution for Apple Pencil, these "small details" that changed user habits all came from his engineering team.

The Apple vision for the Ternus era:

1. The "embodiment" of AI: Compared to cloud-based conversations, Ternus places greater emphasis on "on-device AI." Future iPhones and Macs will become true AI computing centers, with privacy protection hard-coded into the transistors.

2. Robotics and home: As a mechanical engineer, he is highly likely to accelerate the rollout of Apple's smart robots (like a home hub with a robotic arm), extending Apple's ecosystem from fingertips into physical space.

3. The ultimate goal of spatial computing: Reducing the weight and making Vision Pro more everyday is his top engineering challenge. His goal is to make "spatial computing" as simple as putting on a pair of black-framed glasses.

As an engineer CEO who understands physical structures and loves delving into details, the future Apple will be even more focused on products.
