You do get used to the syntax, at which point returning to languages that are prefix here, infix there, statements one way, expressions another, can wrinkle your nose a bit. But syntactic patterns are a question of emphasis; they establish a grain to go with. Lisp's syntax is so uniform as to have no grain. That puts more responsibility on you in exchange for high level flexibility—you can do things the way you want, and a creative method won't be against the grain like it might be in another language.

As for the recursion part, that's more true of Scheme, and it serves SICP's purpose of explaining that iterative and recursive processes can each be generated by recursive code. Common Lisp and friends do have iterative options for loops. But you will probably work in aggregate list operators more than touching a loop yourself.
