Tim Cook is the guy you hire to squeeze more money from your existing customer base. He is not the guy you hire to create new cool things.

I both don't disagree with this really, but also, as an ops person, yes it is crazy hard building some of the most micro miniature systems on the planet and having someone who can see to the details of production is a pretty vital skill.

Still not a customer facing / product development role. At the same time though, again, so much of what makes Apple's products so good is that they have been amazing at product having to work with manufacturing to push the bounds of what is possible. Apple Vision for example taps this intersection: part of the product very much was figuring out physically what it was you could build.

(Something about the past year has really really shifted my perspective, enhanced the already huge respect I have for people making physical things.)
