> Essentially you become an expert in writing 100-200 lines of code that reads data from standard input and prints data to standard output. Useful for CP, not so much in the real world.

Skills from CP transfer very well to the current FAANG interview coding olympics. Add some soft skills and you can easily land a job where you can learn the rest of the things you're listing there, while getting paid. So I wouldn't say there's not much use in the real world.
