When the show finally ends, and there was no treasure to be found, what will Rick and Marty's feelings be?

Twenty years – nearly a generation – they've chased this Oak Island phantom since 2006. Worth it? Well, they haven't found treasure. So, besides the bromance and keeping us viewers (yes, fools, perhaps) vaguely amused, what's the tangible takeaway? And let's be honest, we've collectively sunk days – maybe weeks – of our own precious time into this saga. If no treasure emerges, and the mystery deepens, was it all just an elaborate exercise in futility? You have to wonder what the real point of it all is.
