the chair

On August 31, 2026, Tim Cook ran Apple for the last time.

He had been running it for fifteen years. When he started, in August 2011, Apple was worth approximately $350 billion. It is now worth approximately four trillion dollars. That is an increase of about 3.65 trillion dollars, which is the kind of number that appears to have been typed by someone hitting additional keys accidentally, except that it has not.

Cook's method was not to invent things. Steve Jobs invented things. Cook's method was to know exactly where every component was, at every factory, in every country, ahead of every holiday, before anyone in the room understood that components were the entire subject. He called this operations. The rest of the industry called it something they also did not fully understand. The result was four trillion dollars.

(He also made the iPhones. But mainly he knew where the components were.)

On September 1, John Ternus becomes the chief executive officer of Apple. Ternus is fifty years old, has worked at Apple since 2001, and has spent the last several years overseeing hardware engineering. He is the person who will now know where the components are going next.

Cook will become executive chairman. The title is traditional for this situation. It means he will continue to be present in a formal sense, will advise in an unspecified sense, and will be called upon to engage with policymakers — Apple's announcement used this phrase — in a sense that has not been further defined. He will not be executing.

The word "executive" will remain in his title. It will mean something slightly different.

The components will keep moving.
