'Tim Cook is a legend,' OpenAI CEO Sam Altman posted on X.
After leading Apple for nearly 15 years, Tim Cook will step down as CEO later this year. His tenure marks a major era in the company’s journey, during which Apple became one of the most valuable companies in the world. Cook will move into the role of executive chairman, where he will continue to be involved in key decisions, including strategy and policy matters. He described this shift as a transition rather than a departure.
SurveyCook took over as CEO in 2011, succeeding Steve Jobs during a crucial time. Under his leadership, Apple expanded its product ecosystem, strengthening key areas such as the iPhone, Apple Watch and its services business.

I could not be more confident in his abilities and his character.’
