This is something that has only recently begun to puzzle me as I have an AI in my current project, I've noticed various AI being referred to by gender in certain media E.g. Halo series, Red Dwarf and mass effect. Could someone pleas explain to me how one would decide when it's appropriate to call an AI by gender. I get that if they have their own body you could refer to them as male or female, but since they likely wouldn't have reproductive organs would it be correct to refer to them by gender. For a clearer example, In the Mass effect series the ship "Normandy" has an AI, in it's first series appearance it has nothing to indicate it would be a woman except for it's voice and it's feminine name "E.D.I". Most members of the crew refer to "E.D.I" as a she. I always thought that you could not refer to an AI by gender unless it was completely self aware and chose a permanent gender for itself, is it just a matter of personal preference? Thank you in advance for your replies, please include your own views on the topic too as it adds to the discussion on a whole .
