computer science, or "Informatik/informatique" how some Europeans call it, was a branch of mathematics, and "the industry" pushed _very_ hard to get it "practical", make colleges and universities produce programmers, not computer scientists.
so they removed all "challenging" maths requirements from the curriculum, and you can graduate with much less formal rigour, and certainly without being a matematician.
that's also how python replaced scheme as a first teaching language.
