If we can't understand "typos" how can we possibly tell design?

Are you serious? One can detect design without fully understanding the purposes of a designed product. That's like opening up the hood of a BMW. You know it's designed but you may not know what a certain component does.

I don't need to open the hood of a BMW to tell you what's in there is designed.

Seems that you are adept at detecting design in places you already expect to find design.

Designed or not designed?
