This feels like a lot of blog posts I write: the main content is probably there, in the author's head, but not enough of it was put on the paper. What we read instead is a slice of what I have no doubt in my mind to be a fantastic essay. I have recently begun a love affair with Racket and for a reason I think that the author was ultimately trying to get at: the core syntax of any Lisp is a minimalist tree and the semantics are lambda calculus (and abstract algebra to help motivate types). An REPL for Java could conceivably be written; AI is language agnostic; and plenty of languages let you eval generated code; but Lisps are a window into computation itself and it's very addicting.
