I mean, he's better than you at everything.
Imagine you're one of the millions of people in Eorzea.
You're captain of the guard, then this guy comes along and in a day does your job better than you do.
You've worked as a chef your whole life and in a week this guy is cooking for the sultana.
Noone buys your furniture anymore, cause this guy can churn out 100 desks an hour, make from organs taken from gods.
