I described what I do for a living to him (reading code for subtle mistakes), and he said "that sounds like one of the worst imaginable jobs ever". He is a builder. I find great interest in finding bugs. Writing code is actually an easier job: it is well defined with inputs, outputs and your keyboard in between. Human error, in contrast, could be anything. Someone made a typo. Someone used a compiler that had a bug. Or the CPU had a bug. Or they didn't ship the product right. Or they wrote the password on a postit. Human error is unbounded, which is what makes it so intellectually challenging and interesting to find.
