Hmm, It seems so on the surface. I'm on my third trip through, and it's going to take me less than a month and a half. It really gets substantially easier once you "grok" it. The first time is AWFUL though. This isn't to say of course that I don't get very much out of subsequent readings. SICP is very deep. It's just after a first reading (and doing all the exercises) you're free to focus on concepts more than "tactics."
