> What did he do as a student to gain this level of expertise? Can't we just duplicate that?
I did what I ask my students to do: I studied, and I thought about what I was studying. And "we" can't duplicate that; students must.
Many of them are willing to study. But few are willing to think about what they are studying.
It is very easy to convince students that they are thinking deeply, and most of them will love you for doing so. But it very difficult to get them to actually think deeply. And almost all of them will hate you for doing so.
