I really appreciate the feedback (I'm the author), I definitely expected this sort of response as I was writing it.

I think I got a lot right when I set the level but having seen it in the wild there are things I would have done differently too.

Mostly I wanted people to get excited and see that they could do this right now and that there were good reasons to. I never intended to compete with Norvig, more to create something that would inspire them to want to read it.
