Now, if I had to name a person for Father of All Unit Testing Advocates, I
think I knew who'd I name... ;)

Personally, I think you're right. I've become fascinated with the idea of
unit testing myself, but the problem is that 

a) you often have to find out bugs from somebody else's code

b) you've developed system using testing, but the bug didn't appear in
   your tests and now you don't know what causes the problem 

c) you didn't do unit testing yet when you coded the module or

d) you don't believe in unit testing

to which we'd say d is the wrong answer, c is more likely and a and b just
happen.
