I heard more than once from coworkers and people online that the book Structure and Interpretations of Computer Programs has had a profound impact on them.
I read this book lightly on a few trips but haven't gotten the "eureka" moment from it just yet. What (topic, concepts, etc.) specifically in this book open up your eyes to something or enlightens you? In what way has it made you see things differently than before (if at all)?
Obviously you should have already read this book to comment on this thread.
