I don't care how young he is it is the job of anyone to know the history of their chosen field.
Can't say that I disagree with you, at least in theory.
However, there's a lot we don't know: we don't know if AK was kidding around, we don't know if he was being deceptive to "look cool to his peeps", and we don't know much about what else AK does know about golf. He sure knows a lot more about going low in a big time event than anyone on here, that's for certain.
While the rest of us were learning about the history of golf, or our respective professions, or going to school, playing other sports, doing pretty much anything, AK was just playing golf. Like it or not, people who are at the top of their profession tend to be obsessed with the actual practice of that field, be it sports, music, politics, medicine, whatever. That focus is a big part of what gets them to the top (with talent being the obvious other large factor...).
