When new leadership arrives, a long-serving executive's value lies in their deep institutional knowledge and cross-functional relationships. They can act as a crucial bridge, helping synthesize diverse perspectives to guide the new team's vision and ensure a smoother transition.

Former Intel CEO Pat Gelsinger advises that a leader's job is to temper the extremes of market cycles. Instead of being a cheerleader, a CEO must act as a point of reality, ensuring the organization understands that "the high is never as high and the low is never as low."

Cook's potential retirement isn't about failure but preserving his legacy. He could exit after a record-breaking quarter, before the high-stakes AI bets of competitors either collapse the market or prove Apple is too far behind, protecting his track record.

The young Steve Jobs famously vilified IBM in the iconic "1984" ad. However, upon returning to a failing Apple, the older Jobs recognized his own operational weaknesses. He hired a wave of talent from IBM, including Tim Cook, to instill the discipline in logistics, procurement, and manufacturing that he had previously disdained.

Solomon draws a sharp distinction between founders, who can 'anoint themselves' and hire to fill gaps, and those who rise within an established firm. He argues that to become a successor CEO at a company like Goldman Sachs, you must develop a complete skillset by actively improving your weaknesses.

The ultimate differentiator for CEOs over decades isn't just product, but their skill as a capital allocator. Once a company generates cash, the CEO's job shifts to investing it wisely through M&A, R&D, and buybacks, a skill few are trained for but the best master.

Successor CEOs cannot replicate the founder's all-encompassing "working memory" of the company and its products. Recognizing this is key. The role must shift from knowing everything to building a cohesive team and focusing on the few strategic decisions only the CEO can make.

Rumored next CEO John Ternus is known for maintaining existing products, not developing new ones. This suggests Apple may prioritize operational stability and market dominance over the disruptive, visionary leadership embodied by Steve Jobs, signaling a strategic shift for the company's next chapter.

Tim Cook's legacy will be judged not only by Apple's massive growth but by the strategic position he leaves for the next CEO. Unlike Steve Jobs, who left a clear product roadmap, Cook's successor faces an uncertain AI landscape, which could retroactively impact Cook's own historical standing.
