I found it very engaging and entertaining and it really tied together how we get from the very basic building blocks to a computer that can do something useful. As to whether it will be actually educational, it sounds like maybe it won't be for you, but it might be a nice refresher depending on when you were last in school.

Many CS programs just barely touch on the lower level stuff so this is widely relevant to many in the industry. Its also an easy enough read that even if you have no background, you can follow along and get an understanding of how a computer works.
