>Even brilliant programmers get bugs.

I have long espoused Fischer's Corollary: In any piece of software there are at least five bugs. This holds true even after you remove a bug. (iterate as needed)

BTW, I agree with everything that's been said about Feynman; genius, egotistical, great read--not uncommon traits to find conjoined; take, e.g., Isaac Asimov.
