I’ll take an earnest person over a hip person every time, because hip is short-term. Earnest is long-term.
Earnestness is highly underestimated. It comes from the core, while hip is trying to impress you with the surface.
“Hip” people love parodies. But there’s no such thing as a timeless parody, is there? I have more respect for the earnest guy who does something that can last for generations, and that hip people feel the need to parody.
