When programs make you look dumb

I normally attempt to take responsibility for all my actions (or at least I like to fantasize that I do), but if a program allows me to make a single mistake, I consider it the failure of the program (and it's my failure if I wrote that program). I recently wrote on my own facebook wall accidentally, if your first instinct is to say, "wow, you're not that smart", your attitude is holding back progress in software.
