Tim Cook’s Legacy and John Ternus’ Future

by Brandon Gorrell

In January, Bloomberg reporter Mark Gurman predicted that John Ternus would succeed Cook as Apple’s next CEO. The crux of his argument was twofold: Ternus’ relative youth among the pool of potential successors, and the fact that he’s Apple’s “hardware guy.” Gurman said:

“Ternus is 50. Everyone else on the Apple executive team is late 50s through their mid 60s. Turning 66 this year, in the case of Tim Cook. You’re Apple’s board, you like continuity, you like an insider, you like people who know what they’re doing, and who have been there for a while, they know where the bodies are buried.”
“At 50, he’s the only one. Let’s say Tim Cook hangs out for another three to five years. You’re not going to appoint another CEO who’s 65 or 70 years old. He’s the only guy.”
“Apple gets the vast majority of its revenue from hardware. He’s the hardware guy. Have they screwed up any hardware since he’s been in charge? No. He’s a steady hand who knows what he’s doing. He’s really the only choice.”

Yesterday evening, Mark was the one with the scoop: Tim Cook will assume the role of Apple’s Executive Chairman and John Ternus will take the reins of the company. Mark followed up his scoop with internal memos from both Cook and Ternus announcing the transition.

This morning, Ben Thompson published “Tim Cook’s Impeccable Timing,” which eulogizes Cook’s impressive accomplishments at the head of Apple. In the piece he sketches out how while Steve Jobs took the company from 0 to 1 with the iPhone (i.e. created a product that was wholly new to the world), it was Tim Cook’s “operational genius” that “took Apple from 1 to $436 billion in revenue and $118 billion in profit last year.”

There was some discussion on the timeline over whether Tim Cook had simply put Apple on cruise control and lucked out as many big names in tech also saw 10-40x increases in their market caps. But this interpretation ignores the fact that many of the biggest public tech companies in 1980, when Apple IPO’d, are no longer even close to the top of the pack anymore. Xerox, Motorola, Texas Instruments, IBM, and HP fell by the wayside over the past 30 years while Apple built the biggest consumer hardware company on the planet and thrived in the public market.

As Mark Gurman said on TBPN in January, Ternus really is viewed as the ultimate hardware guy at Apple. Rolfe Winkler at WSJ published an article yesterday detailing Ternus’ pedigree with physical products (“If Jobs was a product visionary and Cook a supply chain guru, Ternus is a hardware savant who exists somewhere in the middle.”) Ternus, who has a background in mechanical engineering, has been working at Apple for 25 years, and most recently led hardware engineering for all of Apple’s products. He played a crucial role in the development of Apple AirPods, and redesigned Apple’s computers to use company-designed chips instead of Intel’s.

Ternus is taking over Apple at a time when the company has largely sat on the sidelines of the AI race, going so far as to outsource the technology powering Siri to Google’s Gemini. Ternus will have to somehow manage this dynamic. Ben Thompson wrote about it in November 2025:

Apple’s plans are a bit like the alcoholic who admits that they have a drinking problem, but promises to limit their intake to social occasions. Namely, how exactly does Apple plan on replacing Gemini with its own models when (1) Google has more talent, (2) Google spends far more on infrastructure, and (3) Gemini will be continually increasing from the current level, where it is far ahead of Apple’s efforts? Moreover, there is now a new factor working against Apple: if this white-labeling effort works, then the bar for “good enough” will be much higher than it is currently. Will Apple, after all of the trouble they are going through to fix Siri, actually be willing to tear out a model that works so that they can once again roll their own solution, particularly when that solution hasn’t faced the market pressure of actually working, while Gemini has?

Ternus also needs to turn around the development of Apple’s smart glasses and tabletop robot, which have been plagued by delays and missed deadlines, while the company tries to expand its smart home products and other wearables.

In 1980, the tech giants looked untouchable until they weren’t. Ternus is stepping in at the moment that distinction starts to matter again.
