As Tim Cook prepares to vacate his role as Apple CEO on September 1st and John Ternus assumes control, people have asked me what Cook is like and how he compares to Ternus. I can't say I know either man well, but I do know them and have, over the years, had the opportunity to speak to each of them.
In due time, both will be part of a very small club: men who have stepped into running one of the biggest and most important tech companies on the planet. When Cook took over, it was shortly before one of Apple's most important launches: the iPhone 4S and, not coincidentally, Siri (yes, the original Siri). 15 years later, Ternus becomes Apple CEO at another pivotal moment: the launch of the first folding iPhone (maybe called the iPhone Ultra) and the full release of Siri AI.
