Apple CEO Tim Cook Is Stepping Down

Apple CEO Tim Cook is transitioning to executive chairman on September 1, with hardware engineering chief John Ternus taking over as CEO amid concerns about Apple's perceived lag in AI development. While Cook grew Apple's market cap from $350B to $4T and expanded services revenue tenfold, his successor inherits challenges around AI competitiveness, China supply chain dependencies, and the need to demonstrate product innovation beyond operational excellence. Ternus, a 24-year Apple veteran, will need to accelerate AI integration across Apple's hardware ecosystem while maintaining the company's quality standards and profitable services business.
