You know a lot about CS. Does that include: Computer science is the study of computers, including computational theory, hardware and software design, algorithms and the way humans interact with technology.
Can you determine if a program is computable? Can you design a computer language? Can you solve the problem of ‘readers’ and ‘writers’? Can you design an computer based system for acquiring cognitive information?
If you can do all of these things (and much more) then indeed you may not learn much.
