Interesting to read your experiences. Looking over this, it seems to take a highly theoretical approach and work up, rather than a practical/applied approach and work down. I was surprised to see automata covered so early, which is more in the vein of computability theory than that of introductory concepts.
There are literally dozens of us making great careers solving problems with computers without CS degrees or any particular interest in the lowest levels of computing nor the mathematical backings / abstractions.
