Summary of Key Points
On September 1, 2024, Tim Cook concluded his 15-year tenure as Apple's CEO and assumed the role of Executive Chairman of the Board of Directors, with John Ternus, the Senior Vice President of Hardware Engineering, taking over. Cook's farewell was unique: his public tweet was brief and warm, while his internal letter to employees was over 1,000 words long and emphasized that "culture is more important than anything else." He made no mention of impressive figures such as the company's market value increasing from $350 billion to $4 trillion or its revenue tripling. This transition marked the first smooth and institutionalized change in Apple's 50-year history (announced 4 months in advance with no internal strife), signaling a shift from relying on "genius individuals" to a "system-driven" approach. As a hardware expert, Ternus inherits challenges such as Apple's shortcomings in AI and an aging executive team. The fall event on September 9 (the launch of the foldable iPhone and the new Siri) will be his first major test as CEO.
Cook's Farewell Letter: Why Not Mention the Numbers That Could Be Praised Forever?
Cook's 15-year tenure as CEO yielded remarkable results: a 10-fold increase in market value, annual revenue rising from $108 billion to $416 billion, a service business worth over $100 billion, and 2.5 billion active devices. Any CEO would have proudly displayed these numbers, but Cook's letter did not mention them at all.
What he focused on were the intangible aspects: "What I am most proud of is what you cannot see in the annual reports—the company culture." He specifically cited three individuals: the team for their contributions ("This all comes from you"), Steve Jobs for his vision ("He left a legacy that will impact the world"), and Ternus for his ability to create products that can change the world.
Why did he do this? Cook wanted to show that Apple's success is not due to any one person (Jobs or himself), but rather to a culture that believes in the significance of products and the power to make the world a better place. Just as he transformed Jobs' ideas into products available globally, he aims to create an Apple that can continue to thrive even without him.
Apple's Transition: From Chaos to Smooth Handover
Previous transitions at Apple were chaotic: in 1985, Jobs was ousted by the CEO he had hired, and the company went through three CEOs in 12 years, leading to a chaotic product line and nearly bankruptcy (known as the "Odyssey period"). In 2011, Jobs resigned abruptly and passed away six weeks later, and Cook was appointed as the new CEO in a time of crisis.
This time, everything was different: the transition was announced 4 months in advance, approved unanimously by the board, and Cook will remain as an advisor (with the Executive Chairman handling policy communication), resulting in no market fluctuations. This success is the result of 28 years of "system building" by Cook. He joined Apple in 1998 and helped Jobs streamline inventory management (reducing turnover time from months to days) and later promoted Apple University to integrate Jobs' management philosophy into the company's curriculum, ensuring that leadership is based on a systematic approach rather than on individual geniuses.
In short, while previous transitions were marked by the departure of key figures, this one is supported by a well-established system.
Ternus' Three Challenges: A Hardware Expert Must Overcome AI Shortcomings
Ternus, 51 years old and with a background in mechanical engineering, has been involved in the development of almost all Apple products, including the iPhone, Mac, AirPods, and Vision Pro. However, he faces challenges left over from Cook's era:
Challenge 1: Catching Up with AI
Apple has lagged in AI development: Apple Intelligence failed to meet expectations, and the upgrade of Siri has been delayed, with significant personnel changes within the team. Cook's approach was inconsistent, involving collaborations with OpenAI and Anthropic, and ultimately with Google's Gemini, costing $1 billion annually. Ternus plans to combine hardware and AI by integrating AI capabilities into products like the camera-equipped AirPods and smart glasses, leveraging Apple's strengths in hardware to compensate for software weaknesses.
Challenge 2: Replacing the Old Executive Team
Cook's team remained stable for 15 years, but most of the executives are now nearing retirement and accustomed to old methods. Ternus must lead while also replacing key leaders in hardware and retail departments, which is like "changing tires while driving."
Challenge 3: Defining the Future Direction
Apple has not clearly decided whether to focus on AI. Cook did not provide a definitive answer during his tenure, and Ternus must make a decision: should the company continue to rely on hardware for profits or bet on AI to reinvent its products?
The fall event on September 9 will be the first test of this decision, with the launch of the foldable iPhone (the first product to change its form in nearly a decade) and the new Siri, demonstrating Apple's ability to innovate and keep up with AI trends.
Cook Hasn't "Retired": He's Just Moving to a New Role to Help Apple
Cook's transition to Executive Chairman is not about taking a backseat; he will continue to focus on his strengths, such as working with policymakers around the world to resolve trade issues and negotiate with governments during regulatory changes. These efforts are crucial for Apple's global success.
He said, "The title may change, but my passion remains the same." In essence, he is moving from the driver's seat to the passenger seat, ready to support Ternus as needed. His true legacy is a system that can operate independently of him.
Conclusion: Cook's Odyssey Ends, and Ternus' Begins
Cook transformed Apple from a company led by a genius to one governed by established systems. Now, it's up to Ternus to apply these systems to address the challenges of AI. The launch on September 9 will show whether Apple can continue to make a significant impact in the AI era.
