They should just go with the full aviation crew naming scheme. Rename some of them to FO (first officer), second officer, navigator, flight engineer, radio operator. The cheaper models for quick answers will be the "relief crew". Data filtering and loading would be "loadmaster". Instead of referring to the user as "user" call them "captain". Who doesn't like to feel important and in charge!? Embrace the ridiculousness, at least they will all have some distinctive labels to go by.
