If you're learning, it's better to recreate something exactly as it is, so that you have something against which to verify your output. Plus, not everyone is an idea person, and I'd wager that most devs are implementation people, not idea people.

I’d argue that if you’re learning and are so inexperienced you need to recreate something exactly, you should instead recreate something real and useful—of which there are more examples—than one joke.

Plus, I don’t think I’ve seen another of these which is exactly like this (just extremely close in concept), so the argument doesn’t hold.
