Tim Cook has a bachelor engineering degree but he hasn't been involved in engineering work since the 90s. He's been the head of operations, making business decisions like closing down factories and outsourcing production, since his days at IBM. He is a supply chain wonk, which is why he got an MBA (supply chain management is a core part of business school teachings). This is also easily available information. Cook has been "focused on business and profits" for decades, and yet you act like he is an example of a great "engineer" in charge.
