Tim Cook made Apple unshakeable, now John Ternus has to shake it

Tim Cook took a company built on bets and stopped betting.

He built the supply chain, the services, the margins, and an Apple that absorbs tariffs, lawsuits and a botched AI launch without changing direction.

That durability is now the problem.

John Ternus is the first hardware man in charge in thirty years, and he starts with Cook's desk, Cook's pipeline and Cook down the hall.
