I love Racket, and thus Schemes of many kinds, but that chapter is really difficult for me to read compared to more academic or technical approaches - and I am really not an academic or technical person!

I find the use of some sort of Socratique dialogue to be deeply confusing, distracting and frustrating. Creepy, SCP-foundation or Welcome-to-Nightvale-like asides such as "We did not expect you to know this." only add to my confusion. It makes simple concepts like recursion look like some sort of House of Leaves nightmare world.
