On August 6, Tim Cook stood on the Apple Park stage for the final time as CEO.
Worldwide Developers Conference (WWDC) 2026 - The last dance.
He introduced "Siri AI"-a virtual assistant integrated with Google's Gemini, promising to bring Apple back into the AI race where the company had lagged for the past two years.
In 80 days - September 1, 2026 - Tim Cook will step down as CEO, handing the reins to John Ternus, Senior Vice President of Hardware Engineering.
This is only the second leadership transition in Apple's modern history.
The first-when Steve Jobs handed power to Cook in August 2011-created approximately $3.65 trillion in shareholder value.
However, Cook is not leaving Apple entirely: he will become Executive Chairman of the Board.
Warren Buffett-who has earned over $100 billion in profit from Apple stock-told CNBC this past March:
"Tim Cook couldn't do what Steve did. But Steve dealt him a hand that even Steve couldn't have played as well."
- Warren Buffett, CNBC, March 2026
That statement summarizes everything.
Jobs took Apple from 0 to 1.
Cook took it from 1 to 2.5 billion devices.
At a glance, Tim Cook looks like a manager-a quiet man who wakes up at 3:45 a.m. every day, reads hundreds of emails, hits the gym at 5:00, arrives at the office at 6:00, and possesses a photographic memory sharp enough to spot a wrong figure in a 120-page spreadsheet.
But look closer, and he is the greatest financial architect in American corporate history. Even his harshest critics must admit it:
On the day Apple announced the transition, Donald Trump wrote: "If Steve hadn't been taken from Earth so soon and had run the company instead of Tim, Apple would still have done well-but not as well as it has under Tim."
Sam Altman was more concise: "Tim Cook is a legend."
Tim Cook didn't invent the future-he monetized it. His greatest product wasn't the Apple Watch or AirPods, but the $840 billion buyback machine that Steve Jobs had vehemently opposed.
