I don't really get what your comment has to do with what I said. It seems like a strawman pretending I said, "This book is stupid, I read 100 pages and I still don't know how to make a game!" Or, "this book is stupid, I read 100 pages and I still don't know how to connect to a database!" I'm not even complaining that the exercises are hard, I'm complaining that they're incomprehensible to me. Also, since you've pointed out that the book is called "The Structure and Interpretation of Computer Programs", wouldn't it make more sense for the exercises to be about computer science things instead of math and physics? I own The Art Of Computer Programming by Knuth and it has plenty of exercises in it that are both computer science related and make you think about hard problems.
