It’s a great time for a hardware guy to be running Apple. When John Ternus takes the helm in September as the company’s new CEO, analysts expect Apple to launch a whole new breed of device: a folding iPhone. There are also rumors that we may soon see Apple’s smart glasses and a smart home hub. 

It certainly won’t be a slow start for Ternus, who currently oversees all of Apple’s hardware engineering. But he also will be tasked with navigating new AI and manufacturing challenges, as I explore in this week’s One More Thing episode, embedded below.

CEO Tim Cook passes the baton after 15 years of building Apple into a tech behemoth. Cook was a supply chain and logistics wizard, but perhaps it will take a hardware mind like Ternus to grow Apple in the AI age. My colleagues this week also looked back on Cook’s influence, highlighting the biggest products launched during Cook’s tenure, and his legacy of turning Apple’s gadgets into status symbols. 

But Cook isn’t completely leaving Apple. His influence continues as he takes the role of executive chairman on Apple’s board of directors. You might see him continue to play the role of a Washington whisperer, as the company said Cook will be “engaging with policymakers around the world.”

That leaves Ternus free to focus his energy on new product launches. His first mission? Make sure that enhanced personalized Siri really works well on those fun new gadgets this fall. Because if that flops, it’s going to be a rough first year.
