Well, I know, but usually the choice to pick a gender neutral pronoun is a political point more than a scientific one. Of course, I'm not sure what kind of point they're trying to make. Also, drones are definitely male...and also sex-bots, so...what exactly are they trying to say again? (On the other hand, making male drones effectively eye candy is a political stance that I'm surprised the show didn't take, given Trek's history of fairly progressive politics. Just imagine, wouldn't it be cool if you have a eusocial species that treated males as sex-bots, since their only job is to make babies, and they're useless outside of that one role? Wouldn't that have said something interesting about gender roles?)

I think my point is that Hollywood missed a chance to make a real statement, and the use of gender neutral pronouns was kind of tacked on, instead of a more deliberate choice, which is kind of a shame. We could use a little more female gaze in our entertainment.
