That's more or less what went through my mind when I saw the parts about computation. It would have been amazing as a primer when I first got interested in computers, especially if I had seen it in my youth or several decades ago. Now that I pretty much worked that out by myself it's a lot less more like dejá vu then an ahá moment.
