My, what a big eye you have.
In 2001: A Space Odyssey, we were introduced to HAL 9000—a plucky computer that likes long walks at night, organization, and things not named Dave. In 2010, we found out that we were going to need a bigger boat and that HAL had a sibling: Bob. Or it may have been Phil. It certainly wasn't Knight Industries Two Thousand. It turns out that four years after and five years before, a middle sibling has been discovered: PJ. (Lame, I know. I'm sorry.)
