No. Being a nerd has nothing to do with technology, it has to do with depth of interest and application to study and learning. It can apply to anything, some of the biggest nerds around know nothing about technology but loads about birds or steam trains or plants. Geeks are a _very_ small subset of nerds. In fact, in my opinion, someone who is only interested in technology is not a nerd at all. Nerds are fascinated with detail, no matter what the subject.
