Right, I imagine they wouldn't be seeking out the little grey squares. Humans are curious however and the Wonderer is no different. They might only collect them as they come across them and ponder their meaning and reason for existence in those rare hours they have a little leisure time.
I'd be inclined to think The Wonderer has no use for a computer. Their life is mostly about survival, food, shelter...
But when society is again ready to automate calculations... it's only a hundred years before computing is back.
