That's true enough. But fact is, if someone's ignorant of modulus, I'd say that's scary. Knowing modulus doesn't necessarily demonstrate you have a great grasp of programming. But I think not knowing modulus demonstrates that there's a higher probability you know very little. And fact is, FizzBuzz also filters out all the people who know modulus, but can't figure it out anyway. You definitely don't want those people.
