Tim Cook’s exit is part of a CEO reckoning sweeping Corporate America

The Speed of AI: McMillon cited the urgency around AI as a major catalyst in stepping down, saying he didn’t think he couldn’t finish the transformation he started in time. James Quincey at Coca-Cola essentially said the same thing in handing the reins to COO Henrique Braun. This is a sprint, not a marathon, and requires an athlete at the top of their game. As leadership consultant Stephen Miles told me: “Every company has to run a faster 800 each year and you need someone fit for the 800 who has the longevity to see this through to the other side.”

Keep your legacy intact: Nothing destroys a CEO’s legacy like lingering too long in the job. That may be why Adobe CEO Shantanu Narayen felt compelled to announce he was stepping down after 18 years, before a successor has been found. Tim Cook will leave behind a staggering legacy at Apple, growing a company worth about $300 billion when Steve Jobs died in 2011 to one that’s worth $4 trillion today. But Apple has also lagged on AI, raising questions about whether Cook should lead from here. (It no doubt helps that Ternus is an engineer.)

Transformation is not a turnaround: For all of the tumult in the top ranks, it’s interesting to note that the reins are largely being handed to COOs who understand the company. In a turnaround, boards often go outside to find a new leader who will change the culture, the team, and pretty much whatever else it takes to get results. In a transformation, you want to accelerate change without destroying the house. For the most part, incumbent CEOs know where they want to go. They might even have strong ideas on how to get there. But they recognize the old paradigms of business, from how they organize talent to how they reach customers, is changing at a speed that requires a new leader at the helm.

Data centers’ energy demand skyrockets

A survey of 6,000 CEOs, CFOs, and fellow executives in the U.S. and other countries found that they report few results from AI in their operations, including 90% who said AI has had no impact on employment or productivity over the last three years.
