It is quite long, well written and shares some personal anecdotes, so I really recommend it for anyone interested in the history of the language and its influence.
Hofstadter is probably a good adjunct to any discussion re: LOGO. You could easily believe "Hofstadter's Butterfly" is just a random work of modernist art if you didn't know the science behind it. Pretty much the same with a lot of Artemis Papert's turtle art.
I bemoan the loss of fractal composition and turtle graphics as a mainstream educational thread. Both embody clear visual consequences of repeated application of procedural thinking. We used to train kids that certain types of art can be linked to procedural thinking, where the abstractions involved were much more on the mathematical side. Now we just tell them "download this python package and these 3d model assets" where the abstractions are muddied and focused on tools rather than the thing the tool makes. We're lucky if kids walk away understanding 3d cartesian space.
But I digress...
