Practical questions are boring, mathematically. Engineers get by with the most basic of linear algebra and diffeq. This is boring, mindnumbing mathematics. There are few applications of, say, category theory to real life.
So for the most part, the interesting problems are not in daily life. Most of those have been solved.

...and there you have nicely summed up why CS appeals to me as a field: it is an arena in which interesting, contemporary mathematics can have an immediate and practical application in solving real-world problems.
