If he really means nerds, then he's wrong. We don't need nerds; we do need geeks. There's nothing that nerdiness adds to geekiness that makes nerds more useful than geeks. Quite the opposite: a group of geeks can work together much better than a group of nerds.. A group of really high-quality geeks can even make use of a nerd or two in their midst, but not the other way around.
