You might be saying this in jest but his statement is totally valid if he is a manager.

The level of abstraction you are working on matters. A manager can't just build a great business either. But for example if he encounters legal trouble, he can just hire lawyers to fix it.

His interface to the world is via delegation to people who can solve his subproblems competently and consistently. There's still a "surprising amount of detail" but at a higher abstraction level and solved with different tools(a really strong "biological" AI that can resolve and prevent the details from bubbling up :P).
