I think there are better ways to use SICP. In an institutionally educational setting you'd have peers and mentors to help figuring things out, for example.

Going at it alone is a thing for people that are already alienated by waged labour or whatever, and likely not the most efficient way to learn its lessons, thought it might be the only obviously available. Personally I prefer to dip in for a short while once or thrice a year or when I have something I'd like to get better at that I know it teaches.

Still, neat presentation.
