Imagine for a moment your favorite spy movie, maybe a James Bond movie for example. It’s cast of characters likely consists of five or so core archetypical personas. In this cast you likely have a cunning spy, a love interest, the shrouded head of the spy agency, the maniacal bad guy, and a clever hacker sitting in the background.
