I was among the many confused by the gender-neutral pronouns in audio. At first, I thought is was some sort of sound-system glitch, so I restarted the episode and unplugged and replugged the earbuds. ("Yes, I have worked in computer support. Why do you ask?") Finally, I looked at the printed text and realized that, yup, that really was the sound the narrator meant to make.
Once I got that out of the way, I liked the story, though I continued to find the pronouns a bit distracting. I liked the wordplay with "aux" and "ox," and I was genuinely intrigued by the interplay between the protagonist and the woman. The ending was delightfully creepy, though it would have been even creepier if we'd seen some inkling of what the AI might decide to do with its supposed divinity. Or perhaps its supposed humanity? All sorts of cool ambiguity there...
On the more general subject of gender-neutral pronouns, I agree we're at that awkward figuring-it-out stage for specific individuals. It's clear to me that "their" will replace "his or her" for situations where gender and number are indeterminate, since that's happened in all but the most formal situations and carefully-edited documents. However, as responses to this story make clear, we are a long, long, way from having a standard answer for specific individuals whose gender is unknown or non-binary.
