I have worked with a couple arrogant nerds. I used to look at them and think, you dummies I know a whole lot of things you will never know. When people behave like this I suspect they have some kind of complex.
I was assistant to one of the arrogant ones with the "talk down to people" disease. I was also the person in charge of buying software and computers for the directorate. He would order software for his project and I observed him copying it and taking it home, which was against the rules. I observed this a couple times to be sure. I then went to our boss and suggested he question him on how the software he wanted was used on his project. The boss was literate on the use of software. That ended his software rip off. His couldn't explain why it would be useful.
Most of the ones I worked with were helpful and eager to assist. I remember, in particular, one Canadian fellow who was a jewel.
