Not necessarily - I don't understand how software interacts with, for example, digital cable. I've seen certain channels crash my cable box before. It wouldn't be that surprising to see a certain show reliably crash the cable box.

A topic very much like this one makes up a chapter in the wonderful book Godel, Escher, Bach http://en.wikipedia.org/wiki/G%C3%B6del,_Escher,_Bach

It's a stunningly simple intro to a fairly deep topic: NP completeness, input validation, etc.
