Could you clarify how you reached this conclusion about someone specific, as opposed to a generalized fear such a person might exist?
In many years in the tech/engineering business I have never seen anyone express such a sentiment, despite having worked with more than my fair share of unpleasant people.
Presumption of competence, or obliviousness to one's own advantages are certainly present in the community. But I have not seen anyone express such supremacist ideas before.
