I can see that. He's not Crusoe, but I still found his story interesting because this is someone I usually don't get a chance to talk to (as most recluses are).
And maybe it's my age and experience, but 25-27 years is a really impressive time span to be focused on doing one thing.
I would like to have learned more about how he feels about how the world has changed, he's like Rip Van Winkle or a time traveler in that respect. But most likely as a person who would voluntarily isolate himself from society in the first place, he probably doesn't care about the world.
