Oh boy, I will maybe get flagkilled, but you are wrong: race, sex, clothing, and just about anything easily observable is used by humans to precondition the Bayesian probability of the outcome of any social interaction. I see no reason to expect that AI will be any different in this matter, perhaps only more efficient.

Your username intrigues me (in the context of a discussion about sex determination). Are you by any chance a monotreme?

I'm a cyborg platypus, nice catch. Just two chromosomes is not enough to express all the variations of an algorithmic gender. And by the way, we also sometimes have Z's (but that's considered a racial thing, so no asking).
