For the sake of definition, would your squad from Rainbow Six or something be an AI companion?  Or are we looking for something more personal, like an Alix Vance?  This concept would be helped by a tighter definition.

Anything that follows you around for a fairly long period should be called an AI companion in my opinion

My thinking when I wrote the blurb was that it would include any sort of "bot" that followed you along, whether they were useful (Alyx, squadmates) or useless (nearly every escort quest/mission ever).  That being said, if you wanted to argue that the useless escort objective person isn't a "companion" so much as a "charge," I wouldn't really disagree.
