Given the resemblance of the curriculum to college classes, there are textbooks that would go very well with each category of the curriculum. This would allow people the option to go more in depth into the topics. The foundation of computer science doesn't change much over time so the knowledge in the books will remain viable in the future. Another advantage is that it's generally easier to judge the quality of these books, many people already read and reviewed these books on sites like Amazon.
It will also give people alternatives to these classes. While these classes are great, the platforms that host them (edX, Coursera, etc.) might place more restrictions on free users in the future. This was evident when edX limited audit time and put exercises/problem sets for some classes behind a pay wall.
