I like it how using a stack to implement recursion is an "advanced" topic in SICP
Since Sipser is a real CS book, he started by talking about autonoma, then observed that push down autonoma were more powerful, then observed that push down autonoma could match context free langauges, which are recursive in nature.
And he did that all in like chapter two.
OTOH, no obsessive boasting about lisp.
If you're a lisperatarian who wants your worldview validated, there's nothing better than reading SICP and classical economists.
