I don't understand it but a large percentage of fundamentalist terrorists were engineering/science majors in college, so I wouldn't count on them not having expertise. Also batting for non Islamic homegrown terrorism, Timothy McVeigh was a programmer in his teens, and the Unabomber was a child prodigy, starting college two years early.
