After reading the article, even I found the title tongue in cheek. That said, GP has explicitly called out (quiet well) what he thought was the underlying lesson and I am thankful for that.
It's a bit banal though, of course you should learn something valuable. Isn't that what your mother's been telling you all these years?
I think the better lesson which is directly applicable to all coders is "question your assumptions". To me this was a huge benefit of learning ruby as it happens to be one of the easiest languages to pull your assumptions right out from under you.
